Re: ModelAdmin Media JS file order issue in Django 2.0
because they are specific to only a few models, particularly the loading scripts, and options, etc. this worked great in Django 1.11 On Sunday, 10 December 2017 09:36:56 UTC-5, Etienne Robillard wrote: > > Why don't you simply put the javascripts into your base template without > using Python ? > > Etienne > > Le 2017-12-10 à 09:30, Marc R a écrit : > > I have this in my model: > > class Media: > js = ( >* '/static/plugins/codemirror/lib/codemirror.js',* > '/static/plugins/codemirror/mode/htmlmixed/htmlmixed.js', > '/static/plugins/codemirror/addon/fold/foldcode.js', > '/static/plugins/codemirror/addon/fold/foldgutter.js', > '/static/plugins/codemirror/addon/fold/brace-fold.js', > '/static/plugins/codemirror/addon/fold/indent-fold.js', > '/static/plugins/codemirror/addon/fold/comment-fold.js', > '/static/plugins/codemirror/addon/fold/xml-fold.js', > '/static/plugins/codemirror/addon/comment/comment.js', > '/static/plugins/codemirror/addon/edit/matchbrackets.js', > '/static/plugins/codemirror/addon/edit/matchtags.js', > '/static/plugins/codemirror/mode/javascript/javascript.js', > '/static/plugins/codemirror/mode/xml/xml.js', > '/static/plugins/codemirror/mode/htmlmixed/htmlmixed.js', > '/static/plugins/codemirror/addon/display/fullscreen.js', > '/static/js/admin/syslog/syslog_change_form.min.js' > ) > > which used to work as it was included in the model admin page in the order > it appears.

Re: Passing filter parameters to admin's add view
override the template and change it accordingly (you can grab djangos as a starting point). Google for django admin template override.

Re: Is there a way to tell an instance was saved without checking instalce.pk or doing a db lookup?
What are you trying to accomplish? I believe the doc's talk about this some; but in short, you can only check the pk if its a new object; otherwise the pk would be set (if you retrieved the object from the database, or saved before). I would assume (as i've not run into the issue yet) that on a save() to the object, if it fails you'll get an exceptions thrown.

another ifchanged question, triggers on first call, not what I want
I'm trying to insert breaks when a row value in a specific column of data
changes; however, it is triggering on the very first call to "ifchanged".
For example:
{% for row in report %}
{% ifchanged row.column2 %} {% endifchanged %}
...print other data...
{% endfor %}
The very first line is a "" with the above sample.
Although technically the ifchanged, did change (from Null/None, to some
value), I don't believe the assignment should count as an actual change.
Is there a way around this behaviour?
Thanks,

Re: Admin module - modify SQL Query used for Edit and Save Models

Admin module - modify SQL Query used for Edit and Save Models
I have a model where I have used AES_ENCRYPT(value, key) to save data in a MySQL database. It is set as a varbinary field. So the issue is; when trying to edit the model in Django, it does not render a widget for the field. I've tried the aesfield from github but that does some funky thing with HEX and tagging the type of encryption used. Not what I want, as the database already has 8300 records and other applications that access it using queries like select field1, field2, AES_DECRYPT(field3, 'key') from ... So I can't change how the data is stored or I'll break the other applications. How can I setup customer "SELECT' and "SAVE" (insert, update), queries for a model in django? Or am I stuck creating my own form and processing and related CRUD operations for this Model?

Re: ManyToMany relationship and raw sql queries
did you use Bookmark.objetcs.all().select_related() ? As this will create a join query... at least for your model you show in the message I have found that for very complex joins, you need to use raw query and not a Model.

Re: Django Admin - BooleanField issue
That seems to have worked... I used 1 and 0 as the database is set for a tinyint to store the value (so needs to be 1 or 0). That said, django/python seems to figure that out when saving the value.

Django Admin - BooleanField issue
I've setup a boolean field and get it to display correctly using this in my model: active = models.BooleanField(choices=((1,'yes'),(0,'no'))) However, when I edit a record in the Django Admin, the select field always shows "yes" regardless of the database value. Saving "yes" or "no" stores the correct 1 or 0; is there a bug in the edit form? Or did I miss a setting?
