Re: [Django] #373: Add support for multiple-column primary keys

2022-09-22 Thread Django

Comment (by Clouds):

Hello, the main work of CompoisteField has been done and I'm now working
on `primary_together`/`PrimaryKeyConstraint`.
While I've got several questions:

1. How to write test for migration? (or witch existing test as example)
a. test if the model generating correct models.State
b. test if from OldModel to NewModel would success migrated
2. Shall we have PrimaryKeyConstraint and CompositeField in one PR?
a. primary (without multicolumn) first, then composite
b. composite (cannot set as PK) first, then primary

The main blocker split it into 2 PR might be hard to add meaningful tests
in first PR.

Comment:

It's been about 13 years since this issue was created and about 8 years
since work on it has begun, and it ''still'' hasn't been implemented! Does
the basic functionality at least work? FWIW, AFAIK the main motivation for
this feature is "relationship tables" (i.e. ones that link 2 or more
tables together), which is relatively common. Also, a better API might be
allowing `primary_key` to be set on multiple fields. For my use case, I
don't need to reference the set of columns directly from the database,
just in the view logic. (The item specified by the URL and the current
user are my two primary keys.) I could just use `unique_together`, but I'd
rather not unnecessarily add an extra column. It's not that much of a
problem, but I'd prefer not to need to.

Comment (by konk):

 I apologize for the lack of timely response.

 #19385 looks like it implements the last big piece that is missing from my
 work. I'll need to have a more thorough look at it though.

 The current status of my work is kinda sad. The repo is badly out of date
 because it has become a real pain to keep it in sync with master. I won't
 get into much detail about why here, but I think it isn't worth the effort
 to try to sync it up. Basically, the problem is that I first implemented
 `CompositeField` (in branch `soc2011/composite-fields`) without
 `ForeignKey` support and then I started to refactor `ForeignKey` on top of
 that (`auxiliary_fk_fields`). This has become a real nightmare to
 maintain. I managed to get the branches through the initial Py3k changes
 but that required carefully merging each upstream commit one by one, after
 that there were numerous cleanups in the ORM which I didn't get around to
 merging.

 However, that doesn't mean I'm giving up, I've got other plans. The idea
 is to do it the other way around, first refactor `ForeignKey` and only
 after it works with simple fields, port `CompositeField` on top of it.
 This should still make it possible to reuse most of the code I wrote
 throughout the past two years and make the changes easier to follow.

 I'd like to apply for the upcoming Google Summer of Code with this to
 finally put this to rest, so keep an eye out on django-developers@ for an
 email in the near future.

Comment (by skizzay):

 Jeremy makes a good point about placing primary_key as a constraint within
 Meta.  However, for the interest of time IMO, sticking with the current
 plan is the best path.  Adding primary_key to Meta later as an
 afterthought (assuming the rest of the community finds a need for it)
 should be simple enough without breaking (future) existing code.

 What is the difference between the auxillary_fk_fields and soc2011
 /composite-fields branches?  How often is master merged?  Obviously, this
 isn't a simple change.  Maybe the community could help out a little if
 they had some status of what they could do to help.

Comment (by jeremyt):

 Yeah.. the ideas on this have been plentiful as shown by that thread. The
 optional primary_key Meta option definitely goes with the DRY principle
 that Django is based upon but as long as the scenario is enabled, then I'm
 ok with spelling it out every time.

 This patch plus the work I've done on multi-column joins
 [https://code.djangoproject.com/ticket/19385] should open up some major
 use cases. I lend a helping hand to this issue, as well, to handle any
 concerns.

Comment (by konk):

 Well… The `Meta.primary_key` option was the first proposed API and the
 outcome of [[https://groups.google.com/d/topic/django-
 developers/Y0aAb792cTw/discussion|this discussion]] was that the BDFL
 disliked this option and preferred an explicit `CompositeField`. The
 arguments for either option were mostly a matter of personal preference,
 therefore we settled on the one chosen by Jacob.

 Personally, I don't really care. I can deliver the code for either one,
 there's not that much of a difference as far as the implementation is
 concerned. I'll start a thread on django-developers@ in the upcoming weeks
 regarding the status of this project and my plans, that could be a good
 opportunity for you to bring this up. Just keep in mind that this feature
 has a history of attracting lots of bikeshedding discussions while the
 more serious architectural issues are mostly being ignored. To me, this
 smells more like the former. So, whatever the final decision on django-
 developers@ is, I'll just accept it and write it that way.

Comment (by jeremyt):

 I think the primary_key option in the Meta makes since from the ease of
 use/flow prospective. I'm not saying that we should remove the option from
 the field either but it should only be specified in one space. Just like a
 CREATE TABLE statement really. If I have a primary key of a single column,
 I can specify it on that one column directly but if I have multiple, I
 place the primary key explanation as a constraint and not a column/field
 itself.

 In the end, the model would be the same except the user doesn't have to
 manually declare the composite field(they still can if they want to
 though), but system would generate the composite field for them and make
 it the pk. But if the primary_key is missing everywhere, it continues to
 create the AutoField pk just as it does today.

 Does this disagree with the current schema?

Comment (by konk):

 Adding a `primary_key` option to `Meta` would be redundant, both the
 current API for single-column PKs and the proposed API for composite PKs
 use the `primary_key` boolean flag on a `Field` instance. And as far as I
 understand, attempts to add a new `Meta` option are usually turned down by
 the core team (similar to project-level settings). However, if you have
 good arguments, feel free to state them and this may still be considered.

 As far as the progress goes, there is no timeline. The work is stalled
 once again for lack of time (school and other projects requiring immediate
 attention) but if the core team agrees, I'd like to take this to the final
 stages this summer as part of GSoC.

 Where does this issue stand on the Django timeline? Have we settled on a
 solution (I like the approach of the composite field konk has done). I
 would like to see a primary_key option being placed in the Meta class as
 well.

Comment (by konk):

 Not at all, this is an issue that has been brought up years ago and it
 simply ignited the biggest discussions because this is one of the easiest
 things about this project and practically anyone can give their opinions
 on that. Personally I spent about a few hours thinking about the string
 representation, most of which was spent reading the comments on this
 ticket and then concluding that this is not really an issue.

 More precisely, to implement a working string representation suitable for
 the admin, this is just about everything you need:
 https://github.com/konk/django/blob/soc2011/composite-
 fields/django/db/models/fields/composite.py#L151 and
 https://github.com/konk/django/blob/soc2011/composite-
 fields/django/db/models/fields/composite.py#L135

 There are much more difficult aspects. The work is currently stalled on a
 refactor of `ForeignKey` and friends. I haven't had much time to work on
 this lately because it is the end of semester here and school's been
 keeping me busy but I still intend to work on this when I get a bit of
 free time. Unless someone wants to take over in which case I would be glad
 to assist in any way I can.

 However, one more thing about the string representation, there is one
 nontrivial issue that hasn't been discussed in this ticket at all –
 `GenericForeignKey`. Using `GenericForeignKey` you can create SQL joins
 between the model containing a GFK and an arbitrary model. The value of a
 GFK pointing to a composite primary key should probably be a string, at
 least I don't have any better ideas. However, to be able to create a SQL
 join between the GFK and the composite field, there needs to be a way to
 reproduce the string encoding of the composite value in SQL. Something
 like
 {{{
 #!python
 blog_posts.objects.annotate(Max('comments__date'))
 }}}
 should generate roughly this SQL query:
 {{{
 #!sql
 SELECT blog_posts.date, blog_posts.title, blog_posts.content,
 MAX(comments.date)
 FROM blog_posts INNER JOIN comments ON (comments.object_id =
 PERFORM_ESCAPE(blog_posts.date, blog_posts.title))
 WHERE comments.content_type = '''the content type of blog_posts'''
 GROUP BY (blog_posts.date, blog_posts.title)
 }}}

 The important bit is `PERFORM_ESCAPE(blog_posts.date, blog_posts.title)`
 which should probably be a rather complex SQL expression that takes all
 the constituents of a composite field, turns them into strings, escapes
 them appropriately and generates one output string out of them. This
 expression will necessarily be strongly backend-dependent but the encoding
 should also be consistent across backends.

 The bad thing about this is that we need to get this right on the first
 try. Once we release this feature with a certain encoding, we'll have to
 stick to that because of backwards compatibility, we can't require all
 users of this feature to migrate their data each time we change the
 encoding. With admin URLs this is not an issue as changing the string
 representation there would just result in slightly different URLs but the
 admin would still work just fine.

 Actually, the last sentence is not entirely true with my current
 implementation because the admin also uses parts of the contenttypes
 framework to store the log of admin activity and currently I put the same
 value in there as the one used in the URL, which means that if I changed
 the representation, all of my logged admin activity would point to non-
 existing objects.

Comment (by thisgenericname@…):

 From skimming over the above comments, it seems that one of the biggest
 issues is the representation of composite primary keys in URLs and in
 references to model.pk

 How feasible would it be to have a set of model methods that:

 1) Given a set of primary key fields, return a string representation of
 the composite key with the requirement that this mapping must be 1:1

 2) Given a string representation of a primary key, return some sort of
 structure that identifies what fields should be at which values...
 Essentially the inverse of the above.

 1 allows the generation of URLs, and allows things that examine model.pk
 to continue to function.

 2 creates the framework necessary to support queries that dereference the
 pk, including lookups and possibly foreign keys.

 The one requirement is that the composite-key-to-string bit must produce
 output that has only one possible interpretation... e.g does escaping of
 commas/slashes/whatever as needed.  In the vast majority of cases using
 integer ids, composites can probably be in the form of 1.5  or 1-5 or such
 and escaping is a non-issue.

Comment (by Pawel Suwala ):

 I have bugfixed and ported the `CompositeKey` base class posted by Ravi (4
 years ago!) to work with current django version.

 Here comes the snippet for people who can't wait for real-ck support in
 django.
 {{{
 

 # Base Class for weak-emulation of composite primary key.
 # To have composite keys workaround in your model, follow these steps:
 # Step1: Paste this snippet before your models in models.py
 # Step2: Extend you class from CompositeKeyModel
 # Step3: Define 'unique_together=(("field1","field2","field3"),) in your
 models Meta class
 # Step4: Create db-table by hand.
 #
 # That's it! The save() on the instances of these models should have the
 composite key effect.
 #
 # Send feedback to: pawel.suw...@fsfe.org
 
##
 }}}

 {{{
 #!python
 from django.db import models
 from django.db.models.base import ModelBase

 class CompositeKeyModel(models.Model): pass

 class IntermediateModelBase(ModelBase):
   def __new__(cls, name, bases, attrs):
 if CompositeKeyModel in bases:
   if bases == (CompositeKeyModel,):
 # create the class via the super method
 newclass = ModelBase.__new__(ModelBase, name, (models.Model,),
 attrs)
 # but then make it inherit from our model class
 newclass.__bases__ = (CompositeKeyModel,)
 return newclass
   else: raise Exception, "IntermediateModelBase does not support more
 than one base"

  #contruct model filter on the fly for the fields that listed in
 the
  # 'unique_together' meta attribute

  #use the generated filter to check if the object already exist
  # if so fetch it
  fetched = self.__class__.objects.complex_filter(filter)
  #if fetched, then get its primary key and set it into the object
 instance
  #that is being saved.
  if(len(fetched) > 0):
  pk = self.get_primary_key()

Comment (by konk):

 Well, the current status is, the `soc2011/composite-fields` branch is
 stable and I'm just keeping it up-to-date with master. There is some
 documentation, though I'm afraid it is not complete. Anyway, it only works
 with non-relationship fields.

 As for relationship fields and the `auxiliary_fk_fields` branch, it is
 still only in the refactoring phase. I had to modify `ForeignKey`
 extensively and it's still not there but I'm trying to fix the bugs one by
 one. Once the whole test suite succeeds (except for `CompositeField`
 tests) I can resume working on composite fields themselves.

 Note that this is quite a tedious process since most of the remaining
 failing test cases require individual handling, therefore I'll appreciate
 any help with this. Feel free to fork me on github and send pull requests.
 I don't always find enough free time to work on this myself, I've still
 got some exams to do and also a Bc. thesis to work on...

Comment (by lau):

 We're still a bunch of hopeful people holding our breaths for this feature
 to enter django. What's the status? Looks like there's lots of activity on
 github, is the code at a state where it's reasonably stable? In which case
 I'd be happy to start testing on some real-life data.

Comment (by RaceCondition):

 So, um, what is then the purpose of the CC list if you get messages
 anyway?
 Basically, still, code.djangoproject.com is sending out spam; it's
 irrelevant if it's a feature for some people.

Comment (by aaugustin):

 (off-topic for this ticket)

 !RaceCondition, given
 [https://code.djangoproject.com/ticket/16763#comment:8 the comment you
 left on ticket 16763], it seems that you're aware of the situation.
 Whenever you contribute to a ticket, you will be notified of further
 updates by email.

 We don't intend to change this behavior because many contributors rely on
 it. However, we have a manual procedure to remove people who no longer
 want to receive these emails.
 [https://code.djangoproject.com/ticket/16763#comment:7 Just follow the
 instructions!].

 And of course, don't post while logged-in, or your email will be added to
 the CC list again. As an alternative, I suggest posting without logging in
 and signing your messages.

 removing myself from CC has no effect whatsoever.
