Constantly need to reset django local settings module
I have made two settings files, one for local testing and one for production (heroku). Every time I pull and start working locally I need to run the following two commands for it to work: export DJANGO_SETTINGS_MODULE= DJANGO_SETTINGS_MODULE=projectName.settings_local Without doing so I get the error that the local settings module cannot be found. This error appeared after I tried to have both settings files in a settings folder, which I did not get to work so I put them back in the original place. Does anyone have an idea how I can fix this? -
Get vimeo video info (Python) --- Different responses on Developers API and POSTMAN
When I make authorized call to Developer API to get video info for a specific video then I get response: { ... "files": [ ... ... { "quality": "hd", "type": "video/mp4", "width": 1280, "height": 720, "link": "LINK", "created_time": "Time", "fps": value, "size": size, "md5": "value", "link_secure": "link_source" }, ... ... ], "download": [ ... ... { "quality": "source", "type": "source", "width": 1920, "height": 1080, "expires": "time", "link": "link", "created_time": "time", "fps": value, "size": size, "md5": "value" }, ... ... ] } I am using Pyvimeo==0.3.2 and Pyvimeo==1.0.0 for Vimeo. But when I hit "https://api.vimeo.com/videos/{vimeo_id}" (with Client_id and Authorization) from my server or from POSTMAN then I get only: { ... "download": [ ... { "quality": "source", "type": "source", "width": 1920, "height": 1080, "expires": "time", "link": "link", "created_time": "time", "fps": value, "size": size, "md5": "value" }, ... ] ... } There is not key "files" in API response. Why I am not getting "files" key in video response ? There is no any such update in API docs. -

Django: can I omit ".save(commit=False)" in this case?
Here's the snippet from a view function for ModelForm in Django: if form.is_valid(): new_entry = form.save(commit=False) new_entry.topic = topic new_entry.save() Would substituting this code with the following one have the same effect?: if form.is_valid(): form.topic = topic form.save() If so, what is the use of creating new_entry object like in the first example? -

Delete objects with checkboxes

I have read through other post and tried to understand it, but I seem to be missing something. views.py def phase1(request, id): ... if request.POST.get('delete'): Descriptor.objects.filter(id__in=request.POST.getlist('item')).delete() return render(request, 'szenario/phase1.html', context) template phase1.html <ul> {% for Descriptor in projectdescriptors %} <li> <tr class="item"> <input type="checkbox" name="item" value="{{Descriptor.name}}"> </tr> {{Descriptor.name}} </li> {% endfor %} <form method="post"> {% csrf_token %} <h1><input type="submit" name="delete" value="Delete selected descriptors" /></h1> </form> </ul Pressing the button reloads the page, but the selected entries are still there. What am i doing wrong? Any help is appreciated. Note: I aim on using AJAX and signals as soon as i understand how to use them, but for now i just wanted to make a simple solution to focus on other tasks. -
how to add markers and center map in signup form django-map-widget
using django-map-widget to render a google map so that user can pick his location on the map. it works fine, but... I would like to trigger the map in two ways (dynamically via javascript): 1. trigger to re-center map on x,y 2. trigger to add a marker to map on x,y I tried so many ways, but i can't solve this. Here are just a few of my attempts: var locationRio = {lat: -22.915, lng: -43.197}; var marker = new google.maps.Marker({ position: locationRio, title: 'Hello World!' }); marker.setMap($("#location-map-elem").map); and var locationRio = {lat: -22.915, lng: -43.197}; var marker = new google.maps.Marker({ position: locationRio, map: $("#location-map-elem").map, title: 'Hello World!' }); You can see and play with the form here Thanks in advance :) -
Maintain git with different settings.py for development and production
I have a Bitbucket repo which interacts with my remote server to push production code for my live Django website. However I want to interact with my Bitbucket repo from my local desktop repo - where I want to test development code before pushing to my Bitbucket which is my production. The only file I don't want to push from my local repo is settings.py as it's different for production and development. I can't add it to .gitignore as I still need it to be pushed from my bitbucket repo to my remote server. Any idea what I should do? -

How to properly submit only one form in table of ModelForms in Django?
I need to create a table of forms for creating and updating users based on my custom User model. It must look something like this: Form is presented as particular row in table. Save button saves submits form, Delete removes form and the model instance from database, Add button appends new blank form to end of <tbody> but to save new form we need to click Save button. Now I'm stuck and don't know how to properly implement logic above. I need each form to be updated and submitted independently. I looked up for solutions based on ModelFormSet but it submits all forms and does not allow to update only one particular row of data. How we can create prepopulated ModelFormSet where each row of form data can be submitted regardless of other forms in table? Like this: <form action="" method="post"> <tr> <td>1</td> <td> <input type="text" name="username" value="admin" maxlength="255" class="login-input" id="id_username" /></td> <td> <input type="text" name="password" value="" maxlength="128" class="password-input" id="id_password" /></td> <td> <input type="text" name="email" maxlength="255" class="email-input" id="id_email" /></td> <td> <input type="checkbox" name="active" class="checkbox-input" id="id_active" checked /></td> <td> <input type="checkbox" name="staff" class="checkbox-input" id="id_staff" checked /></td> <td> <input type="checkbox" name="reboot_field" class="checkbox-input" id="id_reboot_field" checked /></td> <td><button type="submit" form="form1">Save</button></td> <td><button form="form1" >Delete</button></td> <tr> … -

Clean email field when new user is registering in Django?
As I know, standard new user process registration is validate email field only for exists and equals for E-mail Schemas. But users may be write e-mail address like this: JOHN_DOE@MAIL.COM (via Caps Lock) and save it to DB. It's would be dangerous, because other user can register account for these email, but in lowercase: john_doe@mail.com or similar, but still that email address! So, question now is "how to clean up email address when user is registering?". My ideas: set email to lowercase before save to DB check if it exist/unique in DB (in lowercase view, of course) only after, send to user success of error messages -

Django Rest FrameWork Secure Open API
I am developing a Django Rest API which is being used by some apps from mobile or web. The communication between APP and webserver must be in REST and the APIs must be private, and only my apps should able to call them for successful results i.e. other people shouldn't be able to send requests from browsers or such. My problem is that there are no user ids and passwords in my app so the solution is either using HMAC (as stated in this post) or using Django-Rest-Framework-API-Key. my problem is I have no experience in implementing HMAC myself and I can't find a library or package for Django to do so. is there such thing? and I am not sure if Django-Rest-Framework-API-Key will do what I want? thanks in advance. -
build client to client to client chat through server
I'm going to build a Chat with Django (i need this for user profile) that i can access with android and iOS and web platforms. this tutorial could help me a little to understand Socket server, but this is just for a room and uses multi-threading (i have no idea if it makes trouble for many users because when i'm buying VPS, they say that, it handles just one thread! i have no idea what does it mean!) and he doesn't explain how to make client to client chat! actually i had an idea (send user destination id for the server and server can find the socket on the clients dict and sends the message to him) but i think its not safe! i need the best practice -

How to change LetsEncrypt certbot domain?
I'm running my Django application on Digital Ocean with Ubuntu 16.04/Nginx/Gunicorn. I issued a (SSL?) certificate by running the following command: sudo certbot --authenticator webroot --webroot-path /home/user/app --installer nginx -d aaa.com -d www.aaa.com however I now want to change my domain from aaa.com to bbb.com. How do I keep my certificate for my new domain? When I ran the command to issue the certificate, I assume it created various files such as the directory .well-known - and also added code in my Nginx conf. So do I simply run the same command again, with the new domain in? sudo certbot --authenticator webroot --webroot-path /home/user/app --installer nginx -d bbb.com -d www.bbb.com or do I just change the current code and replace it with the new domain? E.g. my Nginx conf looks like this: ssl_certificate /etc/letsencrypt/live/aaa.com/fullchain.pem; # managed by Ce$ ssl_certificate_key /etc/letsencrypt/live/aaa.com/privkey.pem; # managed by $ include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot I've already changed: server { listen 80; server_name 172.128.67.232 bbb.com www.bbb.com; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/user/app; } to my new domain bbb.com. Advice appreciated.
