[web2py] newbie question - recursively finding children
Hey everyone! Wow Web2py 2.0 looks so cool! I can't wait to try all the new features. This has made it so easy for me (a non-programmer) to make viable web applications! My question is as follows: For one of my views, each page in my application has a variable number of child pages, each of which can have a variable number of child pages, and so on. I want each child page to have its own div like so: div the big container div div variable number of divs here div/div variable number of child div's here each with their own text /div div How do I write the controllers, so that it recurses as deep as the deepest node and generates those divs?? My design is as follows: Two tables: table1 -id (auto generated) -field for text table2 -id(autogenerated) -parent_id(created from form) -childid(created from form) I know that I have to write a function that returns a div for each, but I just wasnt sure how to do it. Please help! Thanks! --
[web2py] solicitation for help with public health project for lip reading
I am working on many projects, and I figured I would ask for help on here to see if anyone wants to help with this. We are currently working on a project to help hearing impaired people learn to read lips better. When hearing impaired people learn to speak, they must rely on lip reading more than the average person in order to improve their vocabulary. As a result, many hearing impaired people have vocabulary and reading abilities many grade levels below the average person. We are working on a web2py solution to this problem. The basic setup of the site is as follows: Users will come to the site and be able to navigate a categorical list of uploaded words. This program will display videos of people saying words, along with their definition, and use in a sentence. Ideally, users will be able to read the words into their computer microphone and get feedback on computer recognition of their pronunciation. Users can also add entries wikipedia style. On the back end, a select group of users is defined which can allow user entries to be displayed to the public. These users can also edit the uploaded videos/their definitions/and sentences. If you have any interest in helping make this project a success, please let me know. If you want to take over development of this project, we are also willing to pay up to $1500 for a nice looking, complete solution.
[web2py] unable to create application (permissions?)
Hey everyone, I recently upgraded web2py. Afterwards, I am unable to create applications. I chown'd www-data:www-data the web2py directory, so everything is correctly permitted. I also chmod 755 everything. I had a NEWINSTALL file in there, and my deposit folder is there as well. My current applications run, but I can't add another. I restarted apache multiple times. I am running on debian linux/apache. I looked through all the posts and google'd it, tried everything there. Any suggestions?

No, After much trying to no avail these are the symptoms: All Controllers, Views, Tables show up in AppAdmin. No ability to administrate the DB from AppAdmin. No ability to connect to any application while the affected application is installed. I think somehow my database might have been corrupted. I was doing some stupid testing and one of my .table files was corrupted so I deleted it. They only store database structure right?...

Just continues trying to connect to any application. The application is still under development. After your suggestion, I dumped my db and deleted everything from the databases folder. It's working now...not sure what exactly happened.

Deleting .table files can be a problem. Was the app under development and you wouldn't care if you erased the DB? If so (and it's SQLite), you can delete all the files in the database directory and start with a fresh new DB. When you say that it's not working, how exactly does it behave? Do you get any error messages? Have you touched the routes.py file? Another thing to consider is downloading a fresh version of Web2py and then copying the applications over one-by-one.

[web2py] global search form
Hey everyone,
Thank you so much for your help on my previous issues.
I am trying to create a global search form. I followed Massimo's
example on the social networking example to get a great form working.
I then embedded it in a model and posted the view into my common
layout. I followed the slice for the autocomplete widget as well.
However, everytime I submit a DIFFERENT form on the same page, it
posts an error.
I assume that somehow I need to get a form ID as SQLFORM uses. I tried
to create a sqlform.factory field, but I don't know how to set the
attributes _onkeyup and autocomplete in the form.
1.) If I make it a sqlform.factory form, will that fix the submission
problem?
2.) If not, any suggestions on how to do this correctly?
Here is my code in the model.
searchform=FORM(
INPUT(_type=text, _id=person, _name=person,
_onkeyup=getData(this.value);, autocomplete=off),
INPUT(_type=submit, _value=Search))
searchform['_action']=URL('people','search')
if searchform.accepts(request.vars):
tokens=searchform.vars.person.split()
query = reduce(lambda a,b:ab,
[db.auth_user.first_name.contains(k)|
db.auth_user.last_name.contains(k) for k in tokens])
res_people=db(query).select()
else:

A list comprehension might be easier. Note, if you put non-TD elements in a

Thank you very much for your reply. I have made the changes to my

In your code you have many calls to this:
db(db.mydb.id==request.args(0)).select().first()
which could be simplified into the equivalent expression
db.mydb(request.args(0))
You also have this:
records=db(db.mydb.id==request.args(0)).select()
...
counter=len(records)
but id is unique so counter is always only 1 or 0.
You also have:
check=db(db.mydb.id==request.args(0)).select().first()
if check !=None:
else:
row = db(db.mydb.id==request.args(0)).select().first()
so row is exactly like check and therefore always None.
Basically you code is equivalent to this:
def my_func():
if request.args:
row = db.mydb(request.args(0))
counter = 1 if row else 0
if not row: # should be if row?
my_id=row.id # always fails!
(filename, stream)
= db.mydb.myfield.retrieve(row.resourcefield)
myfunc(id,filename,stream)

Dear Massimo,
Thank you in advance for your time just looking. If I can write a
functional web application, you must be brilliant to have created this
software.
I am essentially trying to write a google docs clone with the ability
to add notes.
My users upload documents which a python function uses, modifies, and
then stores the text in the database. The view displays the text from
the page in a set of divs. I then use AJAX to create a note on the
side via a form.
The text from the document and the document title/file are in
different tables. Also, there is not guaranteed to be file text yet,
as not every user that uploads a file will need to see the text, so I
upload the file and get the text in two separate functions.
My workflow is:
1.) check to see if file exists in database
2.) IF it doesnt, make it, and store the text in a table, then get the
text fields.
3.) IF it does, get the text fields from one table and the filename
from another
4.) Display file text in the view
I then use AJAX to add a form which allows the user to add a note next
to the text.

To pass information from one controller to another. I assume it is
poor programming practice then? I taught myself web programming on

I could think of to do this. I think I have seen it in other posted
examples as well.

Instead of a 'page' table you have the table from which you retrieve
the list and, just like in the example, a table to store the comments.
page_id in your case becomes list_id.
I don't see why you need the fields and counter variable. I would move
the for loop to the view and do something like:
{{for row in rows:}}
tr
td{{=row.field_name}}/td
td{{=A('Add comment',_href=URL('addComment',args=row.id))}}/td
/tr
{{pass}}
.. and in the addComment function something like:
db.comment.list_id.default=request.args(0)
form=crud.create(table=db.comment)
I hope this helps you solve the problem.

[web2py] dynamic SQLForm.factory from query
Dear Everyone,
I am still plugging away on web2py and loving it more and more the
better I understand python.
I have a page where a large list is generated from a database query.
Next to each item from the list, I would like to put the ability to
add a comment.
I did this statically by creating X number of forms for X number of
list items displayed on the page, so I know the concept is possible.
Now, I want to make it dynamic. I searched this group, and all over
the web for dynamic form web2py, multiple form web2py, etc. and
all iterations thereof.
I did find these threads:
http://groups.google.com/group/web2py/browse_thread/thread/1f577d46bd535433
https://groups.google.com/forum/#!topic/web2py/nE_-yhDG-3o
The second one seemed closer to what I'm trying to do, but for now, my
problem is much simpler. I have one table, one query, and just a
variable number of fields. I tried every syntax I could muster
blindly trying to pass in a list of fields to SQLFORM or
SQLFORM.factory.
Below is my code, chopped of the unimportant bits for clarity:
def multi_comment():
records=db(myquery).select()
fields=[]
counter=1
for i in records:
fields.append(Field('note','text'))
fields.append(Field('div_id', default=str(counter)))
counter=counter+1
pass
form=SQLFORM.factory(*fields)
return dict(form=form, fields=fields)
I am getting only one field in my form with a div_id of 1. I know
there has to be a simple way to do this, I am just not skilled enough
to do it.
Any suggestions? Also, any help with implementing the db insert after
the form has been processed would be wonderful!
Thank you in advance!
