# django-crud-mixins
|
||||||
|
|
||||||
|
CRUD and form mixins for Django.
|
||||||
|
Useful for single-page-applications using Gridstack.
|
||||||
|
|
||||||
|
# Usage
|
||||||
|
Add to your `requirements.txt` file:
|
||||||
|
```
|
||||||
|
git+https://git.zm.is/XF/django-crud-mixins
|
||||||
|
```
|
||||||
|
|
||||||
|
## View helpers
|
||||||
|
The view helpers help create simple CRUD views for your application. They are geared towards a single-page application using Gridstack, but can be used on full pages as well by specifying a `type` of `page` always.
|
||||||
|
|
||||||
|
The view permission helpers add a `user=request.user` argument to all queryset filters, ensuring your views can only access the data of the requesting user. Additional filters can be set by overriding the `set_extra_args` method (detailed below).
|
||||||
|
|
||||||
|
Import the helpers from your view:
|
||||||
|
```
|
||||||
|
from mixins.views import ObjectCreate, ObjectDelete, ObjectList, ObjectRead, ObjectUpdate
|
||||||
|
```
|
||||||
|
|
||||||
|
Then, add the views:
|
||||||
|
```python
|
||||||
|
class AccountList(LoginRequiredMixin, OTPRequiredMixin, ObjectList):
|
||||||
|
list_template = "partials/account-list.html"
|
||||||
|
model = Account
|
||||||
|
page_title = "List of accounts"
|
||||||
|
|
||||||
|
list_url_name = "accounts"
|
||||||
|
list_url_args = ["type"]
|
||||||
|
|
||||||
|
submit_url_name = "account_create"
|
||||||
|
|
||||||
|
|
||||||
|
class AccountCreate(LoginRequiredMixin, OTPRequiredMixin, ObjectCreate):
|
||||||
|
model = Account
|
||||||
|
form_class = AccountForm
|
||||||
|
|
||||||
|
submit_url_name = "account_create"
|
||||||
|
|
||||||
|
|
||||||
|
class AccountUpdate(LoginRequiredMixin, OTPRequiredMixin, ObjectUpdate):
|
||||||
|
model = Account
|
||||||
|
form_class = AccountForm
|
||||||
|
|
||||||
|
submit_url_name = "account_update"
|
||||||
|
|
||||||
|
|
||||||
|
class AccountDelete(LoginRequiredMixin, OTPRequiredMixin, ObjectDelete):
|
||||||
|
model = Account
|
||||||
|
```
|
||||||
|
|
||||||
|
### Variables
|
||||||
|
These variables can be added to the classes to adjust functionality:
|
||||||
|
|
||||||
|
Basic:
|
||||||
|
* `list_template`: the name of the template for the list view
|
||||||
|
* `model`: the model you want to view with this helper
|
||||||
|
* `page_title`: the page title to render
|
||||||
|
* `page_subtitle`: the page subtitle to render
|
||||||
|
|
||||||
|
List URLs:
|
||||||
|
* `list_url_name`: the name of the list URL to include in the context, passed as `list_url`
|
||||||
|
* `list_url_args`: arguments for the above, taken from view kwargs, or locals
|
||||||
|
|
||||||
|
Submit URLs:
|
||||||
|
* `submit_url_name`: the name of the submit URL to include in the context, passed as `submit_url` -- used in the form
|
||||||
|
* `submit_url_args`: arguments for the above, taken from view kwargs, or locals
|
||||||
|
|
||||||
|
For `ObjectList` only:
|
||||||
|
* `delete_all_url_name`: the name of the delete-all URL to include in the context, passed as `delete_all_url` -- used in the form's "Delete all" button
|
||||||
|
* `widget_options`: options for the Gristack widget
|
||||||
|
|
||||||
|
For `ObjectCreate` and `ObjectUpdate` only:
|
||||||
|
* `hide_cancel`: whether to hide the cancel button in the form
|
||||||
|
|
||||||
|
For `ObjectUpdate` only:
|
||||||
|
* `pk_required`: whether the primary key `pk` is required in the URL kwargs
|
||||||
|
|
||||||
|
### Methods
|
||||||
|
These methods can be added to the classes to adjust functionality:
|
||||||
|
|
||||||
|
For `ObjectCreate` and `ObjectUpdate` only:
|
||||||
|
* `post_save(self, obj)`: called after the object has been saved
|
||||||
|
|
||||||
|
For `ObjectCreate` only:
|
||||||
|
* `pre_save_mutate(self, user, obj)`: called before the object is saved, AbortSave can be raised with an error message to abort the save
|
||||||
|
|
||||||
|
|
||||||
|
These methods can be used on all classes, as they are inherited from the `RestrictedViewMixin`:
|
||||||
|
* `set_extra_args(self, user)`: adjusts the queryset filter with extra parameters, set `self.extra_permission_args` from this method to a dictionary of arguments
|
||||||
|
|
||||||
|
## Form permission helper
|
||||||
|
The form permission helper `RestrictedFormMixin` can be used as a mixin in your forms:
|
||||||
|
```python
|
||||||
|
class YourModelForm(RestrictedFormMixin, ModelForm):
|
||||||
|
class Meta:
|
||||||
|
model = YourModel
|
||||||
|
fields = (
|
||||||
|
"name",
|
||||||
|
)
|
||||||
|
```
|
||||||
|
It's that simple!
|
||||||
|
The form will automatically add a `user=request.user` argument to all queryset filters, ensuring your forms can only access the data of the requesting user.
