Adding report skills feature in SUSI iOS

SUSI.AI is having a various type of Skills that improving the user experience. Skills are powering the SUSI.AI personal chat assistant. SUSI skills have a nice feedback system. We have three different feedback way for SUSI skills, 5-star rating system, posting feedback, and reporting skills.

5-Star Rating – rate skills from 1 (lowest) to 5 (highest) star

Posting Feedback – user can post feedback about particular skill

Report Skill – user can report skill if he/she found it inappropriate

In this post, we will see how reporting skills feature work in SUSI iOS and how it is implemented. You can learn about 5-star rating here and posting feedback feature here.

Adding report skill button –

let reportSkillButton: UIButton = {
        let button = UIButton(type: .system)
        button.contentHorizontalAlignment = .left
        button.setTitle("Report Skill", for: .normal)
        button.setTitleColor(UIColor.iOSGray(), for: .normal)
        button.titleLabel?.font = UIFont.systemFont(ofSize: 16)
        button.translatesAutoresizingMaskIntoConstraints = false
        return button
    }()

In above, we have set translatesAutoresizingMaskIntoConstraints property for false. By default, the property is set to true for any view you programmatically create. If you add views in Interface Builder, the system automatically sets this property to false. If this property’s value is true, the system creates a set of constraints that duplicate the behavior specified by the view’s autoresizing mask.

Setting up report skill button –

We are setting constraints programmatically as we created button programmatically and set translatesAutoresizingMaskIntoConstraints to false. Also, setting a target to the button.

if let delegate = UIApplication.shared.delegate as? AppDelegate, let _ = delegate.currentUser {
            view.addSubview(reportSkillButton)
            reportSkillButton.widthAnchor.constraint(equalToConstant: 140).isActive = true
            reportSkillButton.heightAnchor.constraint(equalToConstant: 32).isActive = true
            reportSkillButton.leftAnchor.constraint(equalTo: contentType.leftAnchor).isActive = true
            reportSkillButton.topAnchor.constraint(equalTo: contentType.bottomAnchor, constant: 8).isActive = true

            reportSkillButton.addTarget(self, action: #selector(reportSkillAction), for: .touchUpInside)
        }

In the above method, we can see that we are only showing button if user is logged-in. Only a logged-in user can report the skill. To check if user is logged in or not, we are using the AppDelegate shared instance where we save the logged-in user globally when the user signs in.

When user clicks the Report Skill button, a popup is open up with a text field for feedback message like below:

This is how UI look like!

When user clicks the Report action after typing feedback message, we are using the following endpoint:

https://api.susi.ai/cms/reportSkill.json

With the following parameters –

  • Model
  • Group
  • Skill
  • Language
  • Access Token
  • Feedback

Here is how we are handling the API call within our app –

func reportSkill(feedbackMessage: String) {
        if let delegate = UIApplication.shared.delegate as? AppDelegate, let user = delegate.currentUser {

            let params = [
                Client.SkillListing.model: skill?.model as AnyObject,
                Client.SkillListing.group: skill?.group as AnyObject,
                Client.SkillListing.skill: skill?.skillKeyName as AnyObject,
                Client.SkillListing.language: Locale.current.languageCode as AnyObject,
                Client.SkillListing.accessToken: user.accessToken as AnyObject,
                Client.SkillListing.feedback: feedbackMessage as AnyObject
            ]

            Client.sharedInstance.reportSkill(params) { (success, error) in
                DispatchQueue.main.async {
                    if success {
                        self.view.makeToast("Skill reported successfully")
                    } else if let error = error {
                        self.view.makeToast(error)
                    }
                }
            }
        }
    }

On successfully reported skill, we show a toast with ‘Skill reported successfully’ message and if there is error reporting the skills, we present the toast with error as a message.

Displaying Skills Feedback on SUSI.AI Android App

SUSI.AI has a feedback system where the user can post feedback for a skill using Android, iOS, and web clients. In skill details screen, the feedback posted by different users is displayed. This blog shows how the feedback from different users can be displayed in the skill details screen under feedback section.

Three of the items from the feedback list are displayed in the skill details screen. To see the entire list of feedback, the user can tap the ‘See All Reviews’ option at the bottom of the list.

The API endpoint that has been used to get skill feedback from the server is https://api.susi.ai/cms/getSkillFeedback.json

The following query params are attached to the above URL to get the specific feedback list :

  • Model
  • Group
  • Language
  • Skill Name

The list received is an array of `Feedback` objects, which hold three values :

  • Feedback String (feedback) – Feedback string posted by a user
  • Email (email) – Email address of the user who posted the feedback
  • Time Stamp – Time of posting feedback

To display feedback, use the RecyclerView. There can be three possible cases:

  • Case – 1: Size of the feedback list is greater than three
    In this case, set the size of the list to three explicitly in the FeedbackAdapter so that only three view holders are inflated. Inflate the fourth view holder with “See All Reviews” text view and make it clickable if the size of the received feedback list is greater than three.
    Also, when the user taps “See All Reviews”, launch an explicit intent to open the Feedback Activity. Set the AllReviewsAdapter for this activity. The size of the list will not be altered here because this activity must show all feedback.
  • Case – 2: Size of the feedback list is less than or equal to three
    In this case simply display the feedback list in the SkillDetailsFragment and there is no need to launch any intent here. Also, “See All Reviews” will not be displayed here.

    Case – 3: Size of the feedback list is zero
    In this case simply display a message that says no feedback has been submitted yet.Here is an example of how a “See All Reviews” screen looks like :

Implementation

First of all, define an XML layout for a feedback item and then create a data class for storing the query params.

data class FetchFeedbackQuery(
       val model: String,
       val group: String,
       val language: String,
       val skill: String
)


Now, make the GET request using Retrofit from the model (M in MVP).

override fun fetchFeedback(query: FetchFeedbackQuery, listener: ISkillDetailsModel.OnFetchFeedbackFinishedListener) {

   fetchFeedbackResponseCall = ClientBuilder.fetchFeedbackCall(query)

   fetchFeedbackResponseCall.enqueue(object : Callback<GetSkillFeedbackResponse> {
       override fun onResponse(call: Call<GetSkillFeedbackResponse>, response: Response<GetSkillFeedbackResponse>) {
           listener.onFetchFeedbackModelSuccess(response)
       }

       override fun onFailure(call: Call<GetSkillFeedbackResponse>, t: Throwable) {
           Timber.e(t)
           listener.onFetchFeedbackError(t)
       }
   })
}

override fun cancelFetchFeedback() {
   fetchFeedbackResponseCall.cancel()
}


The feedback list received in the JSON response can now be used to display the user reviews with the help of custom adapters, keeping in mind the three cases already discussed above.

Displaying Skills Feedback on SUSI iOS

SUSI allows the user to rate the SUSI Skills with the five-star rating system. SUSI offer a good feedback system where the user can post feedback to any skill by using iOS, Android, and Web clients. In Skill Detail, there is a skill feedback text field where the user can write feedback about SUSI Skill. We display the users posted feedbacks on Skill Detail screen. In this post, we will see how the displaying skills feedback feature implemented on SUSI iOS.

Implementation –

We are displaying three feedback on Skill Detail screen, to see all feedback, there is a “See All Review” option, by clicking user is directed to a new screen where he/she can see all feedback related to particular skill.

We use the endpoint below for getting skill feedback from server side –

https://api.susi.ai/cms/getSkillFeedback.json

With the following params:

  • Model
  • Group
  • Language
  • Skill Name

The API endpoint above return the all the feedback array related to particular susi skill. We store feedbacks in an array of Feedback object, which holds three value:

    • Feedback String – Feedback string posted by the user
    • Email – Email address of feedback poster user
    • Time Stamp – Time of posting feedback
class Feedback: NSObject {
var feedbackString: String = ""
var email: String = ""
var timeStamp: String = ""
...
}

To display feedbacks, we are using UITableView with two prototype cells, one for feedbacks and one for “See All Review” option.

There can be different cases eg. when the total number of feedback for skill is less than three or three. When the feedback count is three or less than three, there is no need to show “See All Review” option. Also, tableView height is different for different feedback count. For varying tableView height, we have created an outlet for tableView height constraints and vary accordingly.

@IBOutlet weak var feedbackTableHeighConstraint: NSLayoutConstraint!

Now, let’s see how the number of cells, height for cells and different cells presented according to feedback count with UITableViewDelegate and UITableViewDataSource methods.

Handling number of tableView rows –

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
guard let feedbacks = feedbacks, feedbacks.count > 0 else {
feedbackTableHeighConstraint.constant = 0.0
return 0
}
if feedbacks.count < 4 {
feedbackTableHeighConstraint.constant = CGFloat(72 * feedbacks.count)
return feedbacks.count
} else {
feedbackTableHeighConstraint.constant = 260.0
return 4
}
}

Where feedbacks is the array of Feedback object which holds the feedbacks we are getting from the server side for a skill.

var feedbacks: [Feedback]?

In the above method, we see that how we are handling the number of cells case. Now let’s see how to handle which cells to be present on basis of the number of cells case –

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let feedbacks = feedbacks, feedbacks.count > 0 else {
feedbackTableHeighConstraint.constant = 0.0
return UITableViewCell()
}
if feedbacks.count < 4 {
if let cell = tableView.dequeueReusableCell(withIdentifier: "feedbackDisplayCell", for: indexPath) as? FeedbackDisplayCell {
cell.feedback = feedbacks[indexPath.row - Int(indexPath.row/2)]
return cell
}
} else if feedbacks.count > 3 {
if indexPath.row == 3 {
let cell = tableView.dequeueReusableCell(withIdentifier: "allFeedbackCell", for: indexPath)
return cell
} else {
if let cell = tableView.dequeueReusableCell(withIdentifier: "feedbackDisplayCell", for: indexPath) as? FeedbackDisplayCell {
cell.feedback = feedbacks[indexPath.row]
return cell
}
}
}
return UITableViewCell()
}

If the number of feedbacks is greater than three than we provide “See All Review” option to the user to see all the feedback related to skill. We are displaying all feedbacks using UITableViewController. When the user clicks the “See All Review” option, we pass the feedbacks (Array of all the feedback) to new UITableViewController. By passing feedbacks, we are reducing one network call.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
if let allFeedbackVC = storyboard.instantiateViewController(withIdentifier: "AllFeedbackController") as? AllFeedbackViewController {
allFeedbackVC.feedbacks = self.feedbacks
let nvc = AppNavigationController(rootViewController: allFeedbackVC)
self.present(nvc, animated: true, completion: nil)
}

On all skill feedback screen, we are displaying the full review. For the different size of text, we are setting the different size of cell size by using the method below:

if let feedbacks = feedbacks {
let estimatedLabelHeight = UILabel().heightForLabel(text: feedbacks[indexPath.row].feedbackString, font: UIFont.systemFont(ofSize: 14.0), width: 250.0)
return 64 + estimatedLabelHeight
} else {
return 80
}

Implementing the Feedback section on Skills CMS

In this blog post, we are going to implement the Skill feedback system on the Skills CMS. The features that are added by this implementation are displaying all the comments/feedbacks of the user, ability to add new feedback and also option to edit a previous feedback that was added.

The UI interacts with the back-end server via two APIs –

Detailed explanation of the implementation

  • The first task was to create a separate component for the feedback section – SkillFeedbackCard.js, along with the CSS file SkillFeedbackCard.css
  • Create ES6 function to get all the Feedbacks of a skill,namely getFeedback(), on the parent component, i.e, SkillListing.js
getFeedback = () => {
    let getFeedbackUrl = `${urls.API_URL}/cms/getSkillFeedback.json`;
    let modelValue = 'general';
    this.groupValue = this.props.location.pathname.split('/')[1];
    this.languageValue = this.props.location.pathname.split('/')[3];
    getFeedbackUrl = getFeedbackUrl + '?model=' + modelValue + '&group=' + this.groupValue + '&language=' + this.languageValue + '&skill=' + this.name;

    let self = this;
    // Get skill feedback of the visited skill
    $.ajax({
        url: getFeedbackUrl,
        dataType: 'jsonp',
       crossDomain: true,
        jsonp: 'callback',
        success: function (data) {
            self.saveSkillFeedback(data.feedback);
        },
        error: function(e) {
            console.log(e);
        }
    });
};

saveSkillFeedback = (feedback = []) => {
    this.setState({
        skill_feedback: feedback
    })
}

 

  • This above code contains the function getFeedback(), that makes an API call to the server for getting all the feedbacks. On successfully getting the response, the feedback array of the response is then passed to a function, saveSkillFeedback(), which in turn updates the skill_feedback state, which was declared in the constructor. This re-renders the components and displays the feedback in the UI.
{
  "feedback": [
    {
      "feedback": "Awesome skill!",
      "email": "[email protected]",
      "timestamp": "2018-06-12 19:28:39.297"
    },
    {
      "feedback": "Awesome skill!",
      "email": "[email protected]",
      "timestamp": "2018-06-12 21:35:53.048"
    }
  ],
  "session": {"identity": {
    "type": "host",
    "name": "141.101.98.18_a7ab9c4d",
    "anonymous": true
  }},
  "skill_name": "aboutsusi",
  "accepted": true,
  "message": "Skill feedback fetched"
}

 

  • Then, we go ahead and create the function that is responsible for posting new feedback and editing them as well.
postFeedback = (newFeedback) => {

    let baseUrl = urls.API_URL + '/cms/feedbackSkill.json';
    let modelValue = 'general';
    this.groupValue = this.props.location.pathname.split('/')[1];
    this.languageValue = this.props.location.pathname.split('/')[3];
    let postFeedbackUrl = baseUrl + '?model=' + modelValue + '&group=' + this.groupValue + '&language=' + this.languageValue + '&skill=' + this.name + '&feedback=' + newFeedback + '&access_token='+cookies.get('loggedIn');

    let self = this;
    $.ajax({
        url: postFeedbackUrl,
        dataType: 'jsonp',
        jsonp: 'callback',
        crossDomain: true,
        success: function (data) {
            self.getFeedback()
        },
        error: function(e) {
            console.log(e);
        }
    });
};

 

  • This above code snippet contains the function postFeedback(newFeedback), that takes the user feedback and make an API call to update it on the server.
  • All the required functions are ready. Now we add the SkillFeedbackCard.js component on the SkillListing.js component and pass useful data in the props.
<SkillFeedbackCard
    skill_name={this.state.skill_name}
    skill_feedback={this.state.skill_feedback}
    postFeedback={this.postFeedback}
/>
  • The next step is creating the UI for the SkillFeedbackCard.js component. We have used standard Material-UI components for creating the UI, that includes List, ListItem, Divider, IconButton, etc.
  • Code snippet for the Feedback ListItem  –
<ListItem
    key={index}
    leftAvatar={<CircleImage name={data.email.toUpperCase()} size='40' />}
    primaryText={data.email}
    secondaryText={<p> {data.feedback} </p>}
/>

 

  • The next part of the UI implementation creating option to edit and post feedback.
  • Code snippet for the Post feedback section  –
className=“feedback-textbox”> id=“post-feedback” hintText=“Skill Feedback” defaultValue=“” errorText={this.state.errorText} multiLine={true} fullWidth={true} /> label=“Post” primary={true} backgroundColor={‘#4285f4’} style={{ margin: 10 }} onClick={this.postFeedback} />

 


 

  • For the edit section, I have used a Dialog box for it. Code snippet for the Edit feedback section  –
<Dialog
    title="Edit Feedback"
    actions={actions}
    modal={false}
    open={this.state.openDialog}
    onRequestClose={this.handleClose}
>
    <TextField
        id="edit-feedback"
        hintText="Skill Feedback"
        defaultValue={userFeedback}
        errorText={this.state.errorText}
        multiLine={true}
        fullWidth={true}
    />
</Dialog>

 

This was the implementation for the Skill Feedback System on the Skills CMS and I hope, you found the blog helpful in making the understanding of the implementation better.

Post feedback for SUSI Skills in SUSI iOS

SUSI iOS, web and Android clients allow the user to rate the SUSI Skills in a 5-star rating system. Users can write about how much particular skill is helpful for them or if improvements are needed. Users can rate skills from one to five star as well. Here we will see how to submit feedback for SUSI skills and how it is implemented on SUSI iOS.

How to submit feedback –

  1. Go to Skill Listing Screen < Skill Detail Screen
  2. Scroll to the feedback section
  3. Write feedback about SUSI skill
  4. Click on POST button to post the skill feedback

An anonymous user can not submit skill feedback. You must have to logged-in in order to post skill feedback. If you are not logged-in and click POST button to post skill feedback, an alert is presented with Login option, by clicking Login, the user is directed to Login screen where the user can log in and later can post skill feedback.

Implementation of posting skill feedback –

Google’s Material textfield is used for skill feedback text field. We have assigned TextField class from Material target to skill feedback text field to make it very interactive and give better user experience.

Skill feedback text field in the normal state –

Skill feedback text field in the active state –

When the user clicks POST after writing skill feedback, we check if the user is logged-in or not.

if let delegate = UIApplication.shared.delegate as? AppDelegate, let user = delegate.currentUser {
...
}

We have saved the logged-in user globally using AppDelegate shared method during login and using it here. The AppDelegate is sort of like the entry point for the application. It implements UIApplicationDelegate and contains methods that are called when application launches, when is going to the background (i.e. when the user hit the home key), when it’s opened back up, and more. The AppDelegate object is stored as a property on the UIApplication class and is accessible from anywhere in swift classes.

Case 1: If the user is not logged-in, we show a popup to the user with the login option

By clicking Login, the user is directed to Login screen where the user can log in and later can post skill feedback.

Case 2: If the user is already logged-in, we use the endpoint below for posting skill feedback –

http://api.susi.ai/cms/feedbackSkill.json

ModelWith following parameters –

  • Group
  • Skill
  • Feedback
  • Access token
Client.sharedInstance.postSkillFeedback(postFeedbackParam) { (feedback, success, responseMessage) in
DispatchQueue.main.async {
if success {
self.skillFeedbackTextField.text = ""
self.skillFeedbackTextField.resignFirstResponder()
self.view.makeToast(responseMessage)
} else {
self.view.makeToast(responseMessage)
}
}
}

In return response, we get feedback posted by the user –

{
feedback: "Helpful",
session:
{
...
},
accepted: true,
message: "Skill feedback updated"
}
