Subject: Confusion over ConfigurableProduct
I'm working on a site for selling T-shirts w/custom logos and am
evaluating Satchmo as a possible solution.

Anyway, I've added configurations for various sizes and colors.  Each
t-shirt with a different logo is saved as a separate product.

The problem arises when I try to associate sizes/colors with a
product. I can add *one* variation (e.g., small, white), which duly
appears on the site.  If I try to add a second variation (e.g. medium,
grey), I get the error "Product variation with this product already
exists".  I'm pretty baffled at this point.  How can I have multiple
sizes and colors for a product?

P.S. Unfortunately I wasn't able to try the demo store as load_data.py
failed with an IntegrityError when I tried to load the data (I'm using
psycopg2), so I wasn't able to inspect the demo.

Regards,
Cliff

Hi Cliff,

I can't say anything useful about your products problem, but I'd just  
like to suggest that you use sqlite for running the demo store as  
well as for your development... it's really easy to get it going, and  
it removes a whole layer of potential problems.

HTH, Itai

Cliff, I just made a quick screencast explaining how to add product
variations.  You can get to it here:

Enjoy and please let me know if it helps.

Very cool.  We probably need to do more of these to make it clearer for
folks how all this fits together.

I'm curious why you went this route versus using the "Create Variations"
option on the Configurable Products page?  That would probably be a quicker
process.

Also, if you didn't put in a price, then it's not going to show up properly
in the store.

Does this make sense?

Actually, I seem to have problems using the Create Variations option.  It
doesn't seem to work at the moment, though it used to.  It creates a list of
them at the bottom of the ConfigurableProduct page, but it doesn't actually
add them to the database.

Beyond that, I don't like how (when it works) it forces every permutation
and combination to be created.  It is a pain to delete invalid combos if you
have any reasonably long list of options.  A wizard is badly needed, IMHO.

Good point about the price.  I was just going fast, and doing a fourth take
didn't seem worth it.

Agreed that we need a wizard or some way to make it much easier.  It's
definitely high on my wish list.  I think we're just stuck trying to figure
out how to do it and wanting to wait on the new-forms admin being integrated
back into trunk.

The confusing thing is that the creation process is 2 step.  First, you
associate your options, then save it.  Next time you edit it, chechk the
"Create Variations" option and save it.  Then, it should create all the
options.  The 2 step process is a django issue that I've never been able to
work around.

Wow, thanks.  That's a big help.

It's clear why I was confused now: I didn't realize I had to manually
create a product for each variation (although that explains how I can
have different images for each variation, which was another question I
had).

Thanks again,
Cliff

Subject: Re: Confusion over ConfigurableProduct
Actually what I find confusing (even after watching Bruce's
screencast) is having to set options on multiple products to achieve a
single goal.  The current process is somewhat  backwards from how a
user (assuming I'm anything like a normal user) would think about
it.

You have to:
1. Create a master product
2. Create sub-products (variations to-be)
3. Alter the master product to be configurable
4. Alter each sub-product to be a variation of the master

Frankly I had to watch Bruce's screencast at least four times (and
still embarrassingly couldn't memorize the process properly until I'd
gotten it wrong at least the same number of times).

The product variations are the particular point of pain.  It doesn't
take much math to figure out that the example t-shirt store will
become quickly unmanageable.  5 sizes in 5 colors plus one "master"
results in 26 separate products, each of which has to be edited with a
multi-step process.  At this point you have one "completed" product in
your store.  A store with 100 products probably couldn't be managed
this way since it would require editing 2600 separate items.

I think what would help with overall confusion is to visually present
products that are variations as being distinct from normal or
configurable products (even if they are represented the same
internally).  How they are represented internally isn't relevant to
the user.   I'd suggest doing things like:
- getting rid of the option to add configurations to variations
- remove the category, description, etc from the product page for
variations since it doesn't appear they are ever used.

Possibly more complicated would be to reverse the process for how
variations are created.  Rather than creating a dozen products and
then altering them to be variations, it would be much more convenient
to select all possible variations and then let the software create the
relevant products to match.   Even if aspects of the variations
(price, number in stock, etc) had to be later edited, it would sure
beat adding them all by hand.  Perhaps this is what "create
variations" is supposed to do, but I couldn't figure out how to make
it work (or perhaps, as Bruce mentioned, it's currently broken).

Anyway, I know this part is being refactored, but this is something
that should be considered during that process.

Regards,
Cliff

Thank you, this is exactly the sort of feedback we need.

To be honest, what I ended up doing for my site with a lot of products was
to dump the file as YAML.  I then used macros in TextMate to create all my
variations, finally stuffing the data back in with "loaddata".  Awkward and
not something we can ask people to do in the real world.

Try this and let me know if it is easier:

- From the admin interface, add a new individual Product
- Choose the appropriate Category, Name, etc.  for illustration purposes,
I'm going to create a Satchmo Developer Book.  Also, put in a value for the
price ($25.00) with no expiration or quantity.  Then click save.
- Now, you should see a list of all your products, click on the Satchmo
Developer Book
- At the bottom of your screen, you'll see the option to "Add
ConfigurableProduct"  click on the link
- Select the appropriate Option Group (Book Type) and click Save & Continue
Editing
- Check "Create Variations" and Click the save button

You've now created all the Product Variants for the Satchmo Developer
Handbook.  If you want to tweak specific ProductVariants you can but you
don't have to.

If you follow this process, does it seem a little cleaner?

I realize it's still not optimal but want to make sure you've got the full
flavor of options available to you.  Now, what feedback do you have ;)

Procedurally, this sounds great.  However, when I try it I get this
traceback consistently:

I wonder if my problems stem from using the Django development server
or perhaps Django isn't well-tested on PostgreSQL.

Cliff

Maybe this ticket is the issue -

If you apply the fix does that take care of the problem?
