Using fetch results to return element to component - React
I have a web app built with python/django and I'm trying to use React for the front-end. The app has a template with an empty div (#profile) that is populated via React. There is an attribute on the template that is used to fetch data from the back-end. The data is passed as props to the main function/component (Profile) to instantiate the state. let username = document.getElementById('profile').getAttribute('data-profile'); fetch(`/getFollow/${username}`) .then(response => response.json()) .then(results => { ReactDOM.render(<Profile profile={username} followers={results.follower_count} following={results.following_count}/>, document.querySelector("#profile")); }) The Profile component returns the html elements and contains another function/component (FollowButton) function Profile(props) { const [state, setState] = React.useState({ follower_count: props.followers, following_count: props.following, profile: props.profile }); return ( <div> <br></br> <div class="row justify-content-center"> <h2 id="profile">{state.profile}</h2> <span> <FollowButton profile={state.profile}/> </span> </div> <div class="row justify-content-center"> followers: {state.follower_count} | following: {state.following_count} </div> <br></br> </div> ); } The FollowButton used the passed in prop to make another fetch and based on the results dynamically return a button element. function FollowButton(props){ fetch(`/getFollow/${props.profile}`) .then(response => response.json()) .then(results => { if (results.isFollowing == "True"){ //Return Following button //console.log('following'); <button class="badge badge-pill ml-2 btn-primary">Following</button> } else if (results.isFollowing == "False"){ //Return Follow button //console.log('follow'); <button class="badge badge-pill ml-2 btn-secondary">Follow</button> } else if (results.isFollowing == "Self"){ //No button … -
form.is_valid() on templateview in create case
I have a Product which looks like this: class Product(models.Model): data = models.JSONField() number = models.PositiveIntegerField() store = models.ForeignKey(Store, on_delete = models.CASCADE) and I create a form dynamically that I fill with the values from the database in the update case like this: class ProductUpdateView(TemplateView): def post(self, request, *args, **kwargs): obj = Product.objects.get(pk = kwargs["pk"]) form = ProductForm(request.POST or None, request.FILES, product = obj) if form.is_valid(): for key in form.cleaned_data: ... so far so good, I can use the forms clean method this way to validate my data and save updated data.

Python RegEx: How to conditionally match multiple optional ending characters in a URL
I have to match URLs in my Django re_path function.

Application Error while my Django app successfully deployed
I am leaving a question of why I got an application error after deploying Django successfully. It seems like I could deploy my Django app to Heroku, but I got an error when I wanted to see my app by pressing the "open app" button on the Heroku dashboard. I am ignoring the database, which is Postgres, now. If I only care about the app without any data, I think I should be able to run the code on the Internet. Here is my source code on github, so I want you to check this out. Thanks so much in advance. -
Access domain name inside model function
I have this model class ArticleWithLinks containing method bodyWithLinks(). It returns article's body(text) + strictly formatted string of links formated like: '[3]: http://my.doma.in/articles/some-slug "Good article!"' joined by '\r\n'. For sure, it could be done in more elegant manner but... anyway ;-) It has to be done this way because body+links will be later together processed by markdown while rendering template. Referenced link details like [id] or some-slug or "Title" (packed in other class) I can easily obtain within models.py and even dynamically add /articles/ using get_absolute_url() method. However, as you probably know, this method returns URL without the domain name. I fully understand the concept that models shall not know about context of their usage (request) but I have to inject it before I pass it to markdown processor called in view's template. What is the best way to do that? Pass request (or even better - domain only) to model's bodyWithLinks() as a parameter and join it inside. I've googled it and found something like simple template tag Somehow retreive it inside model function - I've seen Site class from contrib, that contains domain as well Somehow wrap bodyWithLinks() model's method inside views.py and pass it to template with … -

'member_descriptor' object cannot be interpreted as an integer when looping through the timedelta.day

django-social-auth not redirecting to provided next query param for SAML login
I have a django application that uses django-social-auth and allows for three types of SSO authentication, Google, Office 365, and SAML2.0. In the case of SAML2.0, the application allows the end user to specify their own IdP, and to enable that, we have a custom Database SAML Auth class, that allows us to store the users IdP information in the database, and log the user in. This works as expected, and users can sign in with SAML, Google, or Office 365, no problem. The challenge is when I need to be redirected to a specific URL once the login has completed. This is working as expected for Google and Office 365, but not for SAML login. As an example, I have a mobile application that authenticates via OAUTH to the django web application. When that mobile application starts its oauth flow, it goes to the authorization URL, and the gets forwarded to login. The path looks something like this: https://myapp.com/oauth/authorize/?client_id=something https://myapp.com/login/?next=/oauth/authorize/?client_id=something (after selecting sign in with SAML login method) https://myapp.com/login/subdomain/?next=/oauth/authorize/?client_id=something Redirect to IdP Redirect back to assertion consumer url https://myapp.com/login/sso/saml/complete/ Redirect to account page https://myapp.com/manage/ (not https://myapp.com/oauth/authorize/?client_id=something as expected) The frustration of course is that this breaks the oauth flow … -

Disable button until on-demand Celery task runs
Continuation question to my previous problem. I have a button in the Django template that triggers a Celery task. I want to disable the button after the button is clicked. It is a resource-heavy task, and definitely clicking multiple times must be prevented. My initial idea was to have two buttons, and conditionally show one or the other, depending on if the task is running or not. I would somehow (not figured out how yet), using AsyncResult(str(task)).status = "SUCCESS" pass the resulting boolean to the template. Then show the disabled button if False, otherwise the original clickable button. template.html {% if importEnabled == True %} <a class="btn btn-primary btn--full" id="id_import_data_btn" href=" {% url "import_data" company.company_id %}">Import Data</a> {% else %} <a class="btn btn-primary btn--full" disabled="True">Importing Data (button disabled)...</a> views.py def trigger_import_data(request, company_id): task = import_data_for_company.delay(company_id) importEnabled = AsyncResult(str(task)).status == "SUCCESS" return HttpResponseRedirect(reverse_lazy("edit-company-profile")) My second idea was to use JS in the template and disable the button after clicking it. Here I could make the button not function (but not disabled) after click, but it also didn't trigger the celery task, which is bad. Then I tried setting the boolean to session storage, so I could determine the button showing in … -

Django update other user account fields through Model Form (when logged in as admin)
I am building a django project that allows users to singup and then post projects. Apps include a 'users' app and a 'projects' app. I am using @signals so that 'users' create/edit a Profile and the @signals ensure that the underlying django User model is always in synch with the Profile model contained in the 'users' app. I have one Profile for the superuser and this is set up to not only access its own 'user profile' and 'project posts' that it may post, but is also set up to review the projects posted by other users before they can be seen in the public feed of 'project posts'.

Each 'project post' includes a Profile field as a foreign key (one-to-many) The above is working very well - as the superuser can be the sessionid authenticated user and yet update the 'project posts' that belong to a different profile.
