QUESTION
I am trying to effectively make a Reddit clone just for practice with Django and I am trying to set up my upvote/downvote system with just a simple integer(upvote adds one, downvotes subtract one) however when I hit my "upvote" or "downvote" buttons it gives me the error 'str' object has no attribute 'get'
. I have no idea what is causing this and all of the other answers with this error were not at all related, any help would be awesome.

I am hitting a php file and the response returns a string. I can't find the documentation on how to deal with this.
From the google developer doc google developer doc, my fetch is simple

Answered 2021-Jun-11 at 08:11Your PHP isn't returning JSON, it's just returning a string so use .text()
instead.
QUESTION
I generated ca.crt, ica.crt and server.crt. Here gives some details of the certs.
...ANSWER
Answered 2021-Jun-08 at 15:02The problem is that your intermediate CA ica.crt
is no CA at all. It is missing basicConstraints=critical,CA:TRUE
as extension. This means ica.crt
is only a leaf certificate which should not be used to sign other certificates.
While openssl does not complain when using a certificate without such extension for signing, it will not be able to build the trust chain because ica.crt
is not a valid issuer of server.crt
due to the missing CA:TRUE constraint.
Adding the constraints make everything work, i.e.

QUESTION
I am holding a counter in my Firebase which holds the total upvotes for a picture. When the upvote button is pressed, the database should update the counter of that specified counter by 1, which it does. However, it doesn't show the update on the app screen. For example if an image has 8 upvotes, and the button is pressed to upvote, it will still show 8 upvotes on the screen but in the database it will now be 9 upvotes. When I hot refresh the value changes. How can I make both things happen asynchronously? I tried playing around with it and it's always that either it updates the database and the screen stays unchanged, or the screen changes and the database doesn't.
For the functions below, they behave as expected but just not asynchronously on the screen.
The relevant function that increments the followers in the database:
...ANSWER
Answered 2021-Mar-23 at 00:11Currently you have nothing triggering a rebuild from Firebase. You need to return a FutureBuilder
or StreamBuilder
in your getUpvotes
function. That will get notified of changes in the cloud and trigger a re-build.
Here's something to get you started. Return this instead in your getUpvotes
method and complete the stream portion of the StreamBuilder
QUESTION
Between "user" and "comment" there is a padding that I didn't specify, and which I presume comes from the "display: flex;". I want to remove or change the size of the padding, but I can't seem to figure out how. Here is the code:
...ANSWER
Answered 2021-Jun-05 at 16:58The gap between User and Comment is not from any padding related to display flex, but the pre tag used has a default margin of 1em defined by browser.

QUESTION
I'm hoping someone can help me out. I have created a table and have multiple Tabs. Each Tab has different data inside the table. Each table row has a column with a number of votes and I want to sort the rows automatically with the columns that have more votes at the top.
This is my HTML code:
...ANSWER
Answered 2021-Jun-03 at 03:04Having separate arrays for each tab(comedy and horror) worked for me, so you just create a second array and duplicate the javascript functions, using more specific JS selectors.
QUESTION
I have a list of reports that are being shown to the user. I have a-tags that allow the list to be sorted in different ways (last posted, highest upvotes etc.), and I also have separate a-tags that filter down the list according to a particular report variable (report status is open, closed etc.).
I am trying to figure a way out to allow the filter to remain in place when the a-tag to sort the list is pressed, and vice-versa.
What I have tried was setting up a model with the statusId (id set to filter the list) and sortString (string containing "highest_award" or "last_update", used to sort the list in HomeController), but my thinking was completely off.
Is there a clean way to go about this?
Index.cshtml
...ANSWER
Answered 2021-Jun-01 at 21:27my friend, You should also add a 'CurrentFilterName' for each filter tag you have. Ex: ViewData["AwardSort"] should couple with ViewData["CurrentAwardSort"] So when the page reloads when a filter is clicked you send the values to this 'FilterName' and on input value, you put 'CurrentFilteNameValue'. Hopefully, this solves your issue. Wish you the best :)
