Dictionary as string in django template
I have a dictionary in this format: dict = [{ "key1": "value1" "key2": "value2" "key3": "{"name": "", "age": "", "sex": ""}" }, ] NOTE: key3 is a string holding a dictionary On the template I can actually pull key1, key2, key3 since they are straight forward. But, key3 is one more dictionary stored in string. I'm able to do this: {% for eachObj in dict%} { eachObj.key1 } { eachObj.key3 } <!-- This prints whole dictionary--> { eachObj.key3.name } <!-- This line doesn't work since it is a string --> {%endfor%} Is there some way where I can try doing like: JSON.parse(eachObj.key3) inside that for loop? -

HTML is there a way to limit the year to 4 digits in date input
I am developing a django app. I have date input in my form: <input type="date" name="date_of_birth" class="dateinput form-control" required id="id_date_of_birth"> It allows to enter the date with the year having 6 digits, but I wish it was only possible to enter 4. I tried max, max-length attribute with pattern. I also tried to write a simple script: $(function() { $('#id_date_of_birth').change(function() { var date = $(this).val(); console.log(date, 'change') }); }); but it only starts when I change the year. I would like the numbers to loop on 4 digits instead of 6. Can someone give me a hint how to limit the year to only 4 digits? -

Render React Static files with django
Hope you all are doing well I am trying to connect my react frontend to my django REST-API, which doesn't seem to go well at the moment, in the react development server the application is working quite well but as in terms while exporting its static files to django things seem to crash at the point. The following process was followed to achieve the goal run npm run build command to get the build directory within the react app. Copied and pasted the build/static directory to my BASE_DIR Changed my settings.py for the django project to the following STATIC_URL = '/static/' STATICFILE_DIRS=[ os.path.join(BASE_DIR,'static') ] STATIC_ROOT= os.path.join(BASE_DIR,'static-root') and then finally running the command python manage.py collectstatic which copied over 160 files into my static-root directory. This is what my project structure looks like the collectstatic command doesn't seem to copy my react static files in spite the fact that I have mentioned that static directory which contains the react files. Which is the reason that I cannot access my react static files, any help on how to render the react files django or mistakes in my strategy while development would be highly appreciated. -
Download Uploaded Files in Django Admin Action
I am trying to create an admin action in django to download the selected files uploaded by the users. I can view the uploaded file one by one and use the save link as for saving the file/images.

Bootstrap4 HTML page is too big on mobile
I'm a relative noob with bootstrap and css. I've rebuilt this site from the ground up a couple times in the last couple of weeks to try and sort the spacing etc and currently I have the problem that the main section is slightly too big for a mobile screen in the x dimension and can be scrolled, which is obviously unwanted behaviour. I've tried so many configurations and am so confused as to where this apparent right margin is coming from. (The content fills the screen until you scroll leaving a significant sliver of background body colour. I've tried debugging by setting the background colour of different elements and the margin shows black with the body background, but white with main, i.e is between the body and the main. I have tried doing this in my css: html { overflow-y: scroll; overflow-x: hidden; // this solves the problem on a small browser window but not on mobile device. margin: 0; padding: 0; } body { margin: 0; padding: 0; } main { margin: 0; padding: 0; background-color: #000; // this is what i was referring to that leaves a white margin after scrolling if this color is in the … -
