I separate this in two files, like this: export_excel.py and actions.py I tried to treat all possible forms of information that may appear in admin, such as properties, functions and normal fields, always getting the column name verbose_name or short_description depending on the case.
let say the user chooses the name "Elsa Frozen" now his slug would be "Elsa-Frozen-5" it means 4 other people have used the same header now he can go to url: "your website.com/Elsa-Frozen-4" to see other people's Post
Templatetags function to convert the number into numberize method. It usefull to numberize the visitors, users, or other cases.
Get all field data, e.g. for an export.
This snippet shows how to add a `url` field to your API objects, which will then show up as an object in your JSON output. As parameters, you can specify: - `urls`: A list of strings that exist on your URLMan class - `attribute`: The name of the URLMan class on your model, defaults to `"urls"` - `full`: If the full URLs including schema and hostname should be supplied, defaults to `True`
function to parse the string text into json format
This middleware uses Django's Geoip support (https://docs.djangoproject.com/fr/2.2/ref/contrib/gis/geoip2/), as well as axes's package helper to retrieve IP address (since Django's REMOTE_ADDR might be wrong when behind a reverse proxy). Ensure your geolite DB files are up to date (eg. with https://djangosnippets.org/snippets/10674/). The checker is optional, but ensures that security is not broken due to a misspelled/missing GEOIP_COUNTRY_WHITELIST.
This management command updates country and city Geolite databases from Maxmind (binary databases, not CSV ones), for use with Django's builtin Geoip utilities.
Use this to display an object on a page AND be able to process a form on this page. This is just a copy of the [Django docs advice](https://docs.djangoproject.com/en/2.2/topics/class-based-views/mixins/#using-formmixin-with-detailview), but put as a reusable, standalone View.
A form field for a Boolean that forces the user to make a choice from a list of choices. **Use Case** You have a Yes/No question the user must answer, but they may answer it yes or no. You don't want to supply a default because your need to force the user to actively select their answer. If they do not select an answer, the field should raise a validation error, like "This field is required". Normal BooleanField logic is based on a "checkbox", which, when "required" is required to be checked. This logic assumes that an empty value is the same as False -- in fact, there is no way for validators to distinguish between the empty value and False. Based on excellent suggestion from Peter DeGlopper: https://stackoverflow.com/a/56677670/1993525
Requires to install "basicauth" package, which does basic-auth header encoding/decoding cleanly according to RFCs. Could be improved to return a "realm" in case of http401, like in https://djangosnippets.org/snippets/1720/, although I'm not sure it's really useful in django usecases.
Small fix to make https://www.djangosnippets.org/snippets/1779/ compatible with Django 1.11 To use this you'll also need the javascript from https://www.djangosnippets.org/snippets/1780/ I added an overridden optgroups method that can handle the additional tuple and a couple minor things I gathered while investigating for a fix (a default level_indicator of "+--" and changed paths for the JS files. All credits goes to @anentropic :-)
Django's CharField requires a max_length, and TextField displays a multi- line widget, but in Postgres there's no reason to add an arbitrary max thanks to the `varlena` storage format. So this is a TextField that displays as a single line instead of a multiline TextArea.
With this command you can calculate the maintainability index for your whole project. In your settings you have to add a dictionary called `RADON_MI_SETTINGS`. It could be like this: ```python RADON_MI_SETTINGS = { 'paths': ['projectname'], 'exclude': 'projectname/some_app/some_file.py', 'ignore': 'migrations,tests', } ``` I had to add following packages: ``` radon==3.0.1 progress==1.5 plotly==3.7.0 GitPython==2.1.11 ``` Following commands are available: * `python manage.py calculate_maintainability_index` Only display the maintainability index of the project. The average from every file is build by using the logical lines of code per file. * `python manage.py calculate_maintainability_index --init` Go through every commit filtered by their commit_message (is set to “bump version” currently) and calculate the maintainability index for the whole project. This creates a file with the history. * `python manage.py calculate_maintainability_index --showhistory` Display the history of the maintainability_index in a graph in your browser. * `python manage.py calculate_maintainability_index --commit` Calculate the current maintainability_index and append it to your history. Commit your edited history file. * `python manage.py calculate_maintainability_index --fail` Calculate the current maintainability_index and raise an Error, if it is lower than the last entry in your history. Useful for use in an automated pipeline. Hints: * radon has a problem with large lists and dictionaries. If you have a file with a list or dictionary with more than 100 entries, you should exclude it. * To initialize your history you should change the commitmessage filter to something, that suits your needs.
