QUESTION
I am developing a post system with Firestore and to host the image I use Firebase Storage. The user has to fill in 5 fields, and one of them is the image to add. So, in order for the user to select the image, I do this:
...ANSWER
Answered 2021-Jun-04 at 18:29The uploadImage()
method seems to be run asynchronously and the uploadDataOnFirestore
is run right after the uploadImage
without waiting for thee image to be uploaded, hence the image is null
.
To fix this, move the uploadDataOnFirestore
method call in the OnCompleteListener
onComplete
method of the uploadImage task, so that the image has completed uploading before running the uploadDataOnFirestore

QUESTION
Environment:
Python 3.7 Mysql InnoDB
I am trying to collect data from different tables. I have 4 tables:
- tasks,
- category,
- type_task,
- platform
When I execute my SQL request with Python, I get only 3 columns instead of 6:
...ANSWER
Answered 2021-May-22 at 11:49The way you connect to your database using mysql_connection.cursor(dictionary=True)
returns rows as dict
s. The property of a dict
is that it can have unique keys, in your case all the columns have the same name in the table name
. So there can only be one key of that name
.
To overcome this you need to alias your column names like so
SELECT tasks.id, tasks.name as tname, tasks.introduction, platforms.name as pname, type_tasks.name as ttname, categories.name as cname ...
.

QUESTION
I tried to add an already active stream to a new broadcast, and can't get the broadcast started. The steps I took were.
- Created a new Broadcast.
ANSWER
Answered 2021-May-18 at 20:36I figured it out.
Apparently you cannot have a brodcast created with enableAutoStart=true and then add an active stream. It seems that enableAutoStart=true fails the broadcast transition API calls to change the status to testing or live or complete.
To get this to work, I stopped then started sending to the stream, which caused the stream to transition to inactive then back to active. The transition caused the broadcast to start.
Alternatively, to get this to work without the restart of the stream, I did the following:
- create the broadcast with enableAutoStart=false
- bind the active stream to the broadcast (as in the question).
- transition the broadcast to testing, then to live.
This seems to work fine.
Would have been nice to have the error message for transitioning indicate it was the enableAutoStart which was the problem.
QUESTION
the image above shows the output inside mysql Tables. my problem is it cannot get the value of last_inserted_id value in ORDERTABLE, as it is the reference value in ItemTable itemid.
this is my code in SAVEORDER and SAVEITEM
the description =is where I split the Data into a foreach and save it in item table. each split should save each data with corresponding orderid, I tried last_inserted_id and not MaxID as i want it to be done by 1-3 user simultaneously without having problem in data integrity.
...ANSWER
Answered 2021-May-17 at 16:20So I figure it out.
Instead of using SELECT LAST_INSERT_ID() which has some documentation that it only returns the first ID that has been insert. Bradley Grainger offer to use MySqlCommand.InsertLastId;
I've modified it to this.
