#Day76 of #100DaysOfCode

Today was a good day, I made some progress in the restaurants. I have to thank these wonderful two people :hugs: to help me with the concepts I was stuck at, @Josman_Perez_Exposit who is a gem of a person I worked with in my previous team, helped me understand Cloud functions and triggers and how implementation will work from within the app :orange_heart: and another one is my friend Oya from Android Community :purple_heart: who helped me figure out the error with margins.

I made some good progress in Restaurant App. The error in the setting up margins was the linear layout type I used in the XML code. I was using LinearLayoutCompat on which the code was not working. Changing it to LinearLayout and using the same code fixed it.

    private fun setUpUI(location: String) {

        // create the layout params that will be used to define how your
        // button will be displayed
        val params: ViewGroup.MarginLayoutParams= ViewGroup.MarginLayoutParams(
            ViewGroup.MarginLayoutParams.MATCH_PARENT, ViewGroup.MarginLayoutParams.WRAP_CONTENT
        )

        params.setMargins(30,15,30,15) //left, top, right, bottom

        val button = Button(this)
        button.text = location
        button.layoutParams = params
        button.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent))

        linearLayout.addView(button)
        button.setOnClickListener{
            openPartition(location)
        }

    }

XML code (New): 
    <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center"/>

XML Code (Old):
    <androidx.appcompat.widget.LinearLayoutCompat
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center"/>

The UI screen now looks like this:

Location Screen
Location Screen369×685 73.4 KB

I am not able to fix the Map screen yet, I am getting the correct values of both Longitude and Latitude but the marker is not getting displayed on the Map. It can be one of the below or some unfound error

  • gms dependency is not happening,
  • map key needs to be added to manifest file
  • data-binding needs to be added to whole app or removed from Maps Activity

I also implemented Auth Trigger in the app, This fires a function when a new user sign-ups in the app. This will store the data of the user in the new User collection I added.

The POJO class code for User Collection looks like:

open class User (
    @PrimaryKey var _id: String = "",

    var borough: String? = "",

    var email: String = "",

    var friends: RealmList<Friend> = RealmList(),

    var sharedRestaurantId: RealmList<ObjectId> = RealmList(),

    var name: String = ""
): RealmObject() {}

My Function code looks like the below:

exports = async function addNewUser({user}) {
  console.log(JSON.stringify(user));
  const dbName = context.values.get('db_name');
  const users = context.services.get('mongodb-atlas').db(dbName).collection("User");
  const email = user.data.email == undefined ? "" : user.data.email;
  const name = user.data.name == undefined ? "" : user.data.name;
  console.log(`id: ${user.id} name: ${name}`);
  
  try{
    
    users.insertOne({
    _id: user.id,
    borough: `user=${user.id}`,
    email: email,
    name: name,

  });
  } catch(error){
    console.error(error.toString());
    return
  }
};

The borough here is the partition key that is defined for sync. Although it does not make any sense, but at this time, I want to have a functional app before I make any such changes.

My function gives the following error and I don’t know why and how to fix it, I will look at this tomorrow

Error:

db: string required

Logs:
[
  "{\"id\":\"62646c31c76b8cc188123638\",\"type\":\"normal\",\"custom_data\"
:{},\"data\":{\"email\":\"Mary\"},\"identities\"
[{\"id\":\"62646c3175608ee40e94d276\",\"provider_type\":\"local-userpass\"}]}"
]

Until Tomorrow :wave:
