[web2py] Re: Parent - Child Models in a single form
Thinking about this I can't picture it. So do you render the parent- child form on the server? If so do you just render inputs for one child? Or do you pick n number of child forms to render with the parent? I've done parent - child on one form. At least it looked that way to the user. But it was actually two .load forms loaded into a containing .html page using ajax to avoid page refreshes. -Rip On Sep 3, 4:07 pm, portly.shor...@googlemail.com portly.shor...@googlemail.com wrote: I completely agree - one of the really nice things about Django is that it allows you to have parent - child models in a single form.

Re: [web2py] Re: Parent - Child Models in a single form
Dominic, Could you give a high level overview of what is going on here and how you were able to implement the Parent - Child model in a single form? Following your links, I wasn't able to discern where/if the input form was actually accepting values for multiple tables. I need similar functionality to Portly, and don't really want to go the iframe route. Specifically I need to show the 'children' of a table in the same input form as the parent.

Re: [web2py] Re: Parent - Child Models in a single form
Simply dropping this in does not appear to work, I am getting nothing
where the widget ought to be.
In any case, I don't think this is going to work for my case, as a
simply storing mutltiple strings in a single field isn't what I need.
I have another table with ~20 columns.. nutrition information
specifically.
Two types of things have nutrition information, recipes and basic foods.
Basic foods are simple
Name | Type | Nutrition Table Ref
Recipes are quite a bit more complex, but also need to reference the
Nutrtion Table.
Maybe I am just structuring this wrong entirely and should keep the
Nutrition information in the two tables? Since I will have to be
querying the Nutrition table to get both basic Foods and Recipes back, I
think it makes sense to keep the Nutrition information separate.
There is only a one to one correspondence between nutrition information
and another row.. the same row in the nutrition table won't be
referenced by two different rows in either the recipe table or the
basic_foods table.
I hope that this explanation makes clear why I believe your list:string
solution (which is great and I will use else where in this app) does not
solve this particular problem.
Thanks
Geoff

[web2py] Re: Parent - Child Models in a single form
This a good and interesting problem ;) What I knew about sub-forms was done using XFA - xml forms architecture. This was designed to offer intelligence to forms (I.e. as is, on the web and, of course, in PDF). But... that was a beast in itself. I'm not too sure how to go about this with web2py, but web2py is quite the framework in itself and by having to not only to the Gluon libs but also to python at the first layer (in the html itself), I'm certain that something just as fantastic can be achieved. Binding forms to other forms, or there field data as separate forms should be very do-able. Perhaps looking into a container model would be a way to get there? I.e. container A contains maybe a form with customer info, where the data entered can be accessed by container B (defined conditionally) which perhaps contains another Form in overall customer approval process. Both forms separate but acting a a single form (each manageable independently either at the admin level of at the user level (eg. for updates)... ? Once there adding routing capability should be do-able as well (if not already featured in web2py) there are other ways as well, I think it boiles down to a question of choice and whatever if more efficient (and whatever integrates the best with Massimo's great framework). Had I more time, I'd would love take a crack at this (I already need to find the time for some release/source control related tasks discussed in a previous thread as well as the crazy workload of my unending day (and just as crazy) job). but, IMHO, this is a worthy effort and do hope someone makes something with this idea!

[web2py] Re: Parent - Child Models in a single form
Hi Mdipierro firstly thank you so much for Web2Py - the more I look into it the more I love it. I'm slightly confused by your answer however - how would list:string help me input data for two models at once? kind regards Portly On Sep 3, 5:38 pm, mdipierro mdipie...@cs.depaul.edu wrote: With the new list:string it should be easy to create a widget for it.

[web2py] Re: Parent - Child Models in a single form
you are right it would not but it may be a way to store multiple addresses (as a list of strings) without creating a table of addresses.

[web2py] Re: Parent - Child Models in a single form
This sounds a lot like sub-forms (ends up being part of the form, but can be managed separately, even at run time). I worked on Adobe's Form designer (which is bundled with a full version of Acrobat)... if we we don't have sub-forms in web2py, I would strongly recommend we create them :) Mart On Sep 3, 4:14 pm, mdipierro mdipie...@cs.depaul.edu wrote: you are right it would not but it may be a way to store multiple addresses (as a list of strings) without creating a table of addresses.

[web2py] Re: Parent - Child Models in a single form
I completely agree - one of the really nice things about Django is that it allows you to have parent - child models in a single form. The example from Dominic seems quite complex. Could anyone suggest some ideas of how we could implement this functionality within Web2Py - I'm happy to try and code something but as I'm new to Web2Py I'm not even sure where to start. any help at all would be appreciated.
