What is the format of data in the dictionary would be look like if I’ll retrieve data from firebase? When I want to access keys, I only receive Place1, Place2, and Place3. What happened to tags such as “title”?
Additionally, how to remove double quotation from the value?
Edit: Added image of blocks.
You have to use look for the pair key, make a list , walk at all level + required tag name
Dictionary (already you have)
You can use either web or like this
I just showed, like this you can design.
Thank you, and, I have this set of blocks. What will be format of this in the “data” dictionary?
EDIT: I mean, this.
All of your firebase values saved as a dictionary in in the global variable. And you have to look for the key value from this global data dictionary only you can use any label to catch what is present in the dictionary value or you can click the Do it after connecting with companion
Okay, thank you. I’ll just ask what will be the output of this? Was the global title and image variable a list or dictionary?
As per your structure, the result is dictionary… based on my suggestion, the result is individual list…
Both will do good. No issue. Only usage of blocks will vary
I mean, I want to reply to the blocks you sent. What will be the output of of those blocks? Was the global title and image variable a list or dictionary?
Value of Title from Each tag(Place1, Place2… and so on) comes out as a list…
Index 1 of global title will give you title value of the tag place1, likewise you can get it ,but the fact is you need to confirm the order of tags obtained from your firebase. Sometime random will come and you need to order it before proceeding this process. Always use do it function to cross check everytime
Sigh Limited replies.
What’s wrong with this?
Runtime Error
Argument #1 () to ‘com.google.appinventor.components.runtime.util.YailDictionary.walkKeyPath(com.google.appinventor.components.runtime.util.YailObject,java.util.List)’ has wrong type (java.lang.String) (java.lang.String cannot be cast to com.google.appinventor.components.runtime.util.YailObject)
I think i can smell your problem. You must keep the project bucket empty. The above error is due to empty list…
I redesigned the block to remove the " in each item of the list picker…
I see. A nice way of retrieving data from Firebase. Links that are stored in Firebase has “\” backslash and I have managed to replace it. Thank you.
One last thing, can you show me the block of stored data in the “data” dictionary base on my main topic? I don’t know how’s the structure of that. I just want to learn for the next purposes.
Storing time only you could see but retrieving g time it won’t appear.
Json format only it will be stored in firebase
