How can I start the creation of a Django foreign key model instance from the parent form?
I created the following two Django models: class Partner(models.Model): name = models.CharField( max_length = 100, null = False ) zip_code = models.CharField( max_length = 10, null = False ) class Meta: verbose_name_plural = "Partners" def __str__(self): return self.name class Screen(models.Model): name = models.CharField( max_length = 100, null = False ) position = models.CharField( max_length = 100, help_text = "Google Pluscode", null = False ) partner = models.ForeignKey( Partner, on_delete = models.PROTECT, null = False ) class Meta: verbose_name_plural = "Screens" def __str__(self): return self.name When I add a new instance of a screen, I would like to be able to click on a button inside the form and add a new instance of a partner (if it does not exist yet). After the creation of the foreign key instance, it should return to the original form. It is the same mechanism as in the the admin site when you add a new instance of a model (see image below) but I don't know how to implement it. Admin site model creation I have already looked up inline forms but this is not really the mechanism I want to use. I want to have a new HTML-Page or a modal for … -

How do I show specific field in foreign key model, in Django+React app?
so I have a Django+React app, and having trouble with something. Obviously, I've created REST API with Django and fetching it with React. Let me show you the code first. models.py (Django) class Category(models.Model): category_name = models.CharField(max_length = 20) class Content(models.Model): category = models.ManyToManyField(Category) key_line = models.CharField(max_length = 100, null=True) body = models.TextField(blank=True, null=True) views.py (Django) @api_view(['GET']) def book_list(request): books = Content.objects.all() serialized = ContentsSerializer(books, many=True) return Response(serialized.data) React component class Books extends Component { constructor(props){ super(props); this.state = { } } componentDidMount() { this._getBookList(); } _renderBookList = () => { const books = this.state.bookList_object.map((this_book, index) => { return <BakeList key_line={this_book.key_line} body={this_book.body} category={this_book.category} /> }) return books } _getBookList = async () => { const book = await this._callApiBookList(); this.setState({ bookList_object : book }) } _callApiBookList = () => { return fetch("https://api.book.shop/api/books/") .then((response) => response.json()) .catch((err) => console.log(err)) } render() { return( <div>this._renderBookList()</div> ) } BookList.js class CakeList extends Component { constructor(props) { super(props); this.state = { page : 'home' } } render() { return ( <div>{this.props.key_line}</div> <div>{this.props.body}</div> <div>{this.props.category}</div> ) } Now the problem is in the {this.props.category} line in BookList.js component.

How to properly show image stored from a file server to a django HTML template?
I have trouble displaying images stored in a file server to the django template. File server link is \11234.123.123.123\dashboard.jpg (just a sample). It seems like the img src url is being added by the django localhost url prefix to the file server path as follows: http://127.0.0.1:8000/dashboard/\\11234.123.123.123\dashboard.jpg In django template, the img tag is written as: <img class="imgView" src="{{dashboard_image}}" alt="Dashboard画面.jpg"></img> My views.py just sends the image file server URL as text (with value of \11234.123.123.123\dashboard.jpg) to be displayed as image in the HTML page as the django template. But, the image does not show properly as follows. Please help, thank you! -

Django tag like input for a ManyToMany field in a model
Currently, I have an issue where within my model I have two ManyToMany fields that basically need to act like tags. I either need my data to go from my HTML to my view so I can populate it in the view function, or just have it work with some special form type. class MyModel(models.Model): ... skills = models.ManyToManyField(Skill) interests = models.ManyToManyField(Interest) Where Skill and Interest are classes as follows class Skill(models.Model): SKILLS = ( ('0','Skill 1'), ('1', 'Skill 2'), ) name = models.CharField(max_length=50, choices=SKILLS) def __str__(self): return self.name Currently, my form does not pass in the skill or interest and I can get it to populate off checkboxes. But would like to make it a taggable sort of entry used in Bootstrap: http://bootstrap-tagsinput.github.io/bootstrap-tagsinput/examples/. Any advice is greatly appreciated. Thank you. -

Different fieldset for Django admin inline if it's an "extra" form
I think an example is the best way to describe the problem... In Django 2.2, suppose you have a model Foo, and a model Bar that has a foreign key to Foo. Now suppose you set up the Django admin so that Bar instances appear as inlines in the Foo changeview: class BarAdmin(admin.StackedInline): model = Bar extra = 1 class FooAdmin(admin.ModelAdmin): model = Foo inlines = [BarAdmin] Finally, suppose we're looking at the changeview form for an already saved Foo instance called foo1. On that form you'll see inline forms for all existing Bar instances that point to foo1 along with an extra inline form that you can use to create a new Bar instance if you want to. What I'm trying to do is make the fieldsets be slightly different depending on whether the inline form represents a Bar instance that has already been saved or whether it is the "extra" form that does not represent an existing Bar instance. Specifically, a saved Bar should have an additional field that an unsaved, "extra" Bar should not. I've been experimenting with the InlineModelAdmin's "get_fieldsets()" method, but I have not found any way to tell from inside that method whether we're … -

Django inspectdb omitted integer primary key
I have a legacy MySQL db, and I am trying to create Django models from it so I can use the legacy tables in my Django application. I ran inspectdb on the MySQL db and it seemed to import most fields correctly, but failed to import every single primary key and/or id field. Is this the expected behavior? I will admit I'm new to Django but I find it odd that Django wouldn't use a primary key/id in the same way as SQL. The legacy db holds 17 tables, but I'm only showing one since the behavior was the same for all. Thanks for any insight you might have!
