Is it a good practice Django send request to itself
I have a django rest API that serves endpoints. I coded a complex system of permissions from the views, hence the importance of going through the views for my CRUD operations. For a particular need, I must allow an external application to be able to also use a single endpoint to serve all the others. As if this global endpoint were a postal service: we will send information in an envelope: the endpoint to serve, the method, the data ... To avoid writing the same code in several places, I thought from the view of the global endpoint, call the view of one of the endpoints to be served. However, once I get the request in the view, I have to modify it by changing the data, the paths ... to pass it to the other view. But I have to change too much information in the request. So I wonder: can I make an outgoing request to my second endpoint can I use a component as a test Client or Mock do I have to modify the information of the request before calling the second view? What are the best practices? -

Editing a User photo on Django, need to pass request.POST +request.FILES together
I'm a little stuck here, coding newbie and working on my first Django project from scratch.Looked at a couple answers and tried a couple things out but still not working.I'm trying to allow a user to edit their photo.

BD scheme for multiple size versions of a single original image
Specification I'm designing BD scheme for user profile photos. Each user profile photo should have three size versions. Sizes are Large Medium Small Problem What are some DB scheme best practice for such a situation? What I came up with Something a came up with was to make one master image table and three tables for each sizes and relate them with foreign keys. Image Master Table Table: User Profile Image - image id - user(fk) Tables for each sizes Large Table: User Profile Image Large - id - user profile image id(fk) - image url(I use S3 for storing images) Medium Table: User Profile Image Medium - id - user profile image id(fk) - image url(I use S3 for storing images) Small Table: User Profile Image Small - id - user profile image id(fk) - image url(I use S3 for storing images) Additional Info I use Django btw but I think my question is almost purely a DB problem. However if there are any libraries making this problem easy I would like to know. -

react-admin is getting full schema from graphene API
I'm currently following ra-data-graphql-simple documentation https://github.com/marmelab/react-admin/tree/master/packages/ra-data-graphql-simple to connect a RA app to a django-graphene backend. Initial goal is to list all records of a specified model: App.js class App extends Component { constructor() { super(); this.state = { dataProvider: null }; } componentDidMount() { buildGraphQLProvider({ clientOptions: { uri: 'http://mysite:8000/graphql/' }}) .then(dataProvider => this.setState({ dataProvider })); } render() { const { dataProvider } = this.state; if (!dataProvider) { return <div>Loading</div>; } return ( <Admin dataProvider={dataProvider}> <Resource name="model" list={ModelList} /> </Admin> ); } } Modellist JSX: export const ModelList = (props) => { const isSmall = useMediaQuery(theme => theme.breakpoints.down('sm')); return ( <List > {isSmall ? ( <SimpleList primaryText={record => record.id} secondaryText={record => `${record.name} views`} tertiaryText={record => new Date(record.anno).toLocaleDateString()} /> ) : ( <Datagrid> <TextField source="id" /> <TextField source="name" /> <TextField source="anno" /> <EditButton /> </Datagrid> )} </List> ); } RIght now react-admin only shows "Loading..." section of component, and the request made to the API gives complete schema of itself. As I understood, when you state a in RA return jsx, it finds all records of that model in API endpoint, but this one doesnt include any data, but the schema. What I'm missing? -
Changed data after changing name of field in Django models.py
I'm doing and playing around with my own Django project. I tried to change a couple of names of fields in models.py, and tried some ways that I found on google. after some trials, it seemed successful and I played around with my project. But I figured out it's not working out as it had been so I checked my administration page on Django and db browser for sqlite and found that all data of the field I changed in name have been also changed into the name of changed field name that I tried as shown in picture. Does anyone know how to retrieve or bring back my old data? Thanks in advance! picture of changed name of field and its data in models.py -

Can a django template immediately start streaming in chunks to the client without waiting for it to fully render?
I remember working with PHP a long time ago and a webpage would start being streamed to the client directly, then if a php block was found, the stream blocked until the string from the php was returned and then continued sending data to the client. If an exception was found then you could see a chunk of website, and then the exception in the middle of the webpage. I want to be able to send a django template to the client the same way as PHP did. For example: 1. <html> 2. <head> 3. ... 4. </head> 5. <body> 6. hello {{ some_context_variable }} bye 7. </body> 8. </html> If some_context_variable is a long database operation, I want the user to be able to see hello in the browser until some seconds pass and the db operation is solved, then the user would see in the screen something like hello friend bye Can this be done with django views and rendering a django template? If not, could it be done with another template language like jinja2 or another in conjunction with django? Note: I know that django has StreamingHttpResponse, but as I understand it only allows the view to … -
Difference between JSONField and ArrayField

How to handle a POST request from a Django form loaded via a custom template tag?

Django session cookie disappears with DEBUG=True and multiple logins
I have a very odd issue I've encountered with either django or django-cas-ng (or possibly caused by other django tools?). When DEBUG = True, and a user logs in twice (e.g. in different browsers), the second browser appears to override the first, and the session cookie disappears. This doesn't appear to happen DEBUG = False, so is there something about DEBUG = True which could cause this, and if so where's the best place to find about the differences DEBUG makes (I had assumed that DEBUG only printed backtraces on error, but it appears it does more than that)? -
Django __in but return the first matching element
I have this model from django.db import models class TranslatedString(models.Model): lang = models.CharField() key = models.CharField() value = models.CharField() I have these instances of this model: a = TranslatedString(lang="en_US", key="my-string", value="hello world") b = TranslatedString(lang="en_AU", key="my-string", value="g'day world") c = TranslatedString(lang="ja_JP", key="my-string", value="こんにちは世界") And I have this list of languages a user wants preferred_langs = ["en_CA", "en_US", "en_AU", "fr_CA"] which is ordered by preference. I would like to return the value that matches the first item in that list. Even though both a and b would match a query like TranslatedString.objects.filter(key="my-string", lang__in=preferred_langs).first() I want it to be ordered by the list, so that I always get a. I can make a query for each element in preferred_langs and return as soon as I find a matching value, but is there a better option? I'd like to do it in one query. -
How to use vue in django?
Maybe this question sounds silly but still my vue code doesn't want to work. I'm totally new in Vue. I just added script in my <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> And thought it would be enough. Then I wrote the simple piece of code: new Vue({ el: ".seats_displayer", data: { display: "redbox" } }) and the caught element: <div class="seats_displayer"> {{display}} </div> console says that "display" has not been defined. When I type VUE in console it shows me the vue's object. What did I do wrong ? -
