Show and hide elements in different tabs with JQuery
There are a few similar questions but not one that quite answers mine. I have a page with several different tabs, and a Django form with different filters as fields which is used in the template. The form fields 'west_region' and 'east_region' have different choices. I want to show a different filter depending on which tab is open. Can I use JQuery and the hash value to do this? This is my music.html template: {% block page-content %} <div class="card mb-4"> <div class="card-block"> <form class="ui-filter"> <div class="ui-filter--fields"> <!-- West region filter --> <div class="ui-filter--field" id="west-region"> <label for="supplier_elec">Region:</label> <div class="form-full-width">{{ form.west_region }}</div> </div> <!-- East region filter --> <div class="ui-filter--field" id="east-region"> <label for="supplier_gas">Region:</label> <div class="form-full-width">{{ form.east_region }}</div> </div> </div> <div class="ui-filter--submit"> <button class="btn btn-primary btn-block" type="submit">Apply Filters</button> </div> </form> </div> </div> <div class="row"> <div class="col"> <div class="tab-content content py-4"> <div class="tab-pane active container-fluid" id="jazz" role="tabpanel"> <div class="row align-items-center"> <div class="col-sm-8 col-xl-10 col-12"> <h1>Jazz</h1> </div> </div> <h2>Songs</h2> {% include 'jazz.html' %} </div> <div class="tab-pane container-fluid" id="rock" role="tabpanel"> <div class="row align-items-center"> <div class="col-sm-8 col-xl-10 col-12"> <h1>Rock</h1> </div> </div> <h2>Songs</h2> {% include 'rock.html' %} </div> </div> </div> </div> {% endblock %} {% block extrascripts %} <script> $('#music-genre a').click(function(e) { e.preventDefault(); $(this).tab('show'); }); $("ul.nav-tabs > … -

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. But I want to download more than one by selecting and save them to a zip folder for download in one go. I use this download users' pdf in django as reference and created the below code. I was able to download a zip file but when i opened it,it says the zip file is not valid. I believe there is something wrong with querying the file url/writing it to the zip folder. Please assist. import tempfile import zipfile def downloadPic(self, request, queryset): with tempfile.SpooledTemporaryFile() as tmp: with zipfile.ZipFile(tmp, 'w', zipfile.ZIP_DEFLATED) as archive: for index, item in enumerate(queryset): projectUrl = str(item.file.url) + '' fileNameInZip = '%s.zip' % index archive.writestr(fileNameInZip, projectUrl) tmp.seek(0) response = HttpResponse(tmp.read(), content_type='application/x-zip-compressed') response['Content-Disposition'] = 'attachment; filename="pictures.zip"' return response -
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 … -

For some migrations, why `sqlmigrate` shows empty, or the same SQL both directions?
I'm working on upgrading a legacy project, currently still on Python 2.7.18 as the highest Python-2 before upgrade to 3. After upgrading Django from 1.8.13 to 1.11.29, the project requires some database changes (unapplied migrations), and I'm using command python manage.py sqlmigrate to review the SQL statements.
