Django - Query largest date in an ArrayField
I'm making use of Django's postgres ArrayField. Say I have a model like this: from django.db import models from django.contrib.postgres.fields import ArrayField class Event(models.Model): name = models.CharField(max_length=200) dates = ArrayField(models.DateField()) And I want to find the Event with the latest date. Is there a way to build a queryset that can do that? -
How to accomplish rendering templates with AngularJS without refreshing whole page?
I mostly lack the knowledge and vocabulary to being looking into the subject, as I would have already if I could put my Google search in proper terms that would yield helpful results. This is probably pretty basic, so looking to get a basic knowledge so I can dig into it myself. My current intranet web application has, and really only needs, two URLS: https://app/ https://app/dashboard The first is where the user enters their credentials and then it passes them on to the latter. The web application has a navbar and sidebar that should always be there once they are in the dashboard and authenticated. The navbar has really basic stuff like logout, profile, etc., but the sidebar has several dozen tools I am developing. What I would like is for the user to be able to click on any of those tools and have the main content area populate with content that is relevant to that tool. You see this all over the place, but the most recent one I saw that reminded me to ask about this, is here if you scroll down to the Overview and Spec buttons: https://www.bhphotovideo.com/c/product/667336-REG/CAD_E100S_Equitek_E100S_Supercardioid_Large.html Right now, I have my login page (https://app/) … -

Howler JavaScript library iterating audio objects in Django template
Building an app that displays a list of audio objects, the HTML5 audio element is not compatible across all browsers, so I'm using the Howler JS library. So, my Django template is iterating over an included ul element like this: {% for obj in instance.sounds_set.all %} {% include 'sound_detail.html' with sound=obj %} {% endfor %} the sound_detail.html looks like this: <ul><div> <a onclick="play()">Play</a> <a href="/{{sound.id}}/delete/">Delete</a> </div> </ul> and the script which creates the Howler object: function play(){ var sound = new Howl({ src:['{{obj.sound.url}}'], volume: 0.5, }); sound.play();} So, the template iterates over the ul correctly and the delete url deletes the correct object, but the play() function always calls the first audio object in the list, regardless of which ul object the function is called from. How can I get the play button on each ul object to correspond to the correct sound? -

Django Admin collapse inline
I have a Django Model being displayed in the admin as: class DesInline(admin.StackedInline): model = Des_Product extra = 1 fieldsets = [ (None, {'fields': ['id', 'name']}), (None, {'fields': ['description']}), ('Validation', {'fields': ['testing','results'], 'classes': ['collapse']}), ] class DesAdmin(admin.ModelAdmin): list_display = ('name','version') inlines = [DesInline] admin.site.register(Des,DesAdmin) And I have a large number of inline items. Currently the display show all the editable fields of the inline items DesProduct that were previously entered. Is there a way to use css to collapse existing fields of DesProduct that were previously entered so that only the def __str__(self) from the model shows and it is less clutter? I tried adding classes=['collapse']: class DesInline(admin.StackedInline): classes = ['collapse'] model = Des_Product extra = 1 fieldsets = [ (None, {'fields': ['id', 'name']}), (None, {'fields': ['description']}), ('Validation', {'fields': ['testing','results'], 'classes': ['collapse']}), ] But it collapse the whole List instead of just the editable fields.

Django: Redirect Change Password URL
I have the following two URLs: url(r'^change-password/$',django.contrib.auth.views.password_change,{'template_name': 'meta/changepassword.html', 'post_change_redirect': '/password-changed/'},name='change_password'), url(r'^change-passwordiOS/$',django.contrib.auth.views.password_change,{'template_name': 'meta/changepassword.html', 'post_change_redirect': '/password-changed/'},name='change_passwordiOS'), I thought if I used the following within the change password form it would override what URL would be loaded: {% if 'iOS' in request.path %} <input type="hidden" name="next" value="/profileiOS/" /> {% endif %} But when I reach the change password from the url(r'^change-passwordiOS/$' and click the "Change Button" it does not goto the /profileiOS/ as expected but the standard /profile/ URL. Any help would be appreciated.

Gmail is not receiving emails from SendGrid
I have a Django app set up to send emails from my contact form via SendGrid. The contact form should send emails to contact@clientdomain.com, which is an account using G Suite, so the client opens the email on Gmail. However, the emails from the contact form are getting stuck on SendGrid with status deferred or block. I tried changing the destination email from contact@clientdomain.com to personal_email@gmail.com and it worked just fine. I don't know what else to do. Here is my Activity Feed from SendGrid dashboard: I read when the status is deferred, SendGrid keep trying to send the email again for the next 72h, but I have emails sent 3 days ago that never arrived on the inbox. Anyone knows what could I do to fix that? -

Dont reload static files with runserver, django
I load big json files as static files for my page. This takes a few seconds. As ive read and experienced, Django (started with runserver) loads those files again, when my website is refreshed, which is not what I want, because of the loading time. How can i most easily permit this behavior, so that the files are only loaded once when the server is started? Thanks in advance! -

AJAX Form with CBV Django yileds Form_Invalid Response but still posts to DB
Basically, I have a simple form that only has one field, which requires a string of < 200 chars. The form is submitted via an AJAX request and the response should be to stay on the same page("drug_new") and return a success or a fail with details about what was committed to the DB. What actually happens is: POST http://localhost:8000/drug/new/ 400 (Bad Request) And the server log shows the following: [18/Jul/2017 12:53:35] "GET /drug/new/ HTTP/1.1" 200 3909 invalid loop [18/Jul/2017 12:53:37] "POST /drug/new/ HTTP/1.1" 400 37 [18/Jul/2017 12:53:37] "POST /drug/new/ HTTP/1.1" 302 0 [18/Jul/2017 12:53:38] "GET /drug/new/ HTTP/1.1" 200 3909 Somehow the data also gets posted at the DB level, so what gives?? I am thinking it might have something to do with including the csrftokenmiddleware in the data section of the ajax request, however when I try to exclude it, it results in an error 500. I know that I could just use a function based view to validate the form data, however I don't want to have a CBV and a function for the same view. There has to be a way to get the CBV to work with an ajax request. Thanks in advance! :D Here are … -

Django dynamic models disappear after restarting server
In my Django app I create a bunch of models at runtime dynamically. The models are created fine and they are registered properly. However, when I restart the server that my app is running on, the models disappear. The data stays in the database but there is no sign of the models I created. I tried recreating the models with inspectdb but since they are not static models like inspectdb creates, it does not work out properly. I have also tried registering them at database connection, but the issue is that they are not even known as models to begin with. Does anyone know how I can keep my models after restarting? -

How does one redirect on an error in allauth?
I'm currently am writing a site where the users fill out a form with some information to signup, and the server verifies the correctness of that information on its end before allowing a successful signup.

I have only been able to log in the model and do it by admin, but with templates its different. models.py class Connection(models.Model): following = models.ForeignKey(User, related_name='following') follower = models.ForeignKey(User, related_name='follower') date_created = models.DateTimeField(auto_now_add=True) def __str__(self): return "{} > {}".format(self.following.username, self.follower.username) Source: https://github.com/cotizcesar/plaxedpy/blob/master/userprofile/models.py -
Django ModelForm with foreign key - allow user to create a new value
Lets say I have a basic model Recipe class Recipe(models.Model): name = models.CharField(max_length=100, null=True, blank=True, default=default_name) category = models.ForeignKey('Category') instructions = models.CharField(max_length=500, null=True, blank=True) Where Category is a related model. Then I have a basic recipe form: class RecipeForm(ModelForm): class Meta: model = Recipe fields = ['name','category','instructions'] This works fine, and shows correctly a select box with all of the categories to pick from. However I would like to give the user an option to enter in a brand new 'category' if they don't find one that fits in the related Category model. I found a solution using the select2 javascript library that allows the user to type in a custom value, however that causes the form to throw an error: Select a valid choice. That choice is not one of the available choices. What I'd like to do when processing the form, is take the custom inputs, create the new 'Category' object, then bind it back to the form.
