[web2py] Re: rname and reserved names

[Niphlod]

if it's what I think, then 

db = DAL(, check_reserved=None)
db.define_table('easy', 
   Field('position', rname='"difficult_name_for_the_field"'),
rname='"difficult_name_for_table"')

should work (albeit, if it does, it shows "the bug" because if you're using 
rname, then you don't need to check for reserved keywords).

The point of rname (in addition to give the possibility to use the proper 
quoting directly) is also to separate model from the underling structure.

Usually I'm dealing with table names like 
t_ABCD_Alpha_Blocking_Common_Dolls and fields like 
ABCD_CreationDateForTicket (very enteprisey ^_^''') ... until rname my 
code was full of

db(db.t_ABCD_Alpha_Blocking_Common_Dolls.ABCD_CreationDateForTicket > 
request.now).select(db.t_ABCD_Alpha_Blocking_Common_Dolls.ALL)


that eventually turned up to be

tb = db.t_ABCD_Alpha_Blocking_Common_Dolls
db(tb.ABCD_CreationDateForTicket > request.now ).select(tb.ALL)



but it was a vibe-killer.

Now I can

db.define_table('ABCD',
Field('CreateDate', rname='"ABCD_CreationDateForTicket"'),
rname='"t_ABCD_Alpha_Blocking_Common_Dolls"')


and use 

db(db.ABCD.CreateDate > request.now).select(db.ABCD.ALL)

Re: [web2py] Re: rname and reserved names

[Michele Comitini]

You can also use explicit quoting of entities at DAL level.  It works
transparently so you can use the same names in python and in the DB schema.

db = DAL('postgres://...', ...,ignore_field_case=False, entity_quoting=True)


db.define_table('table1', Field('column'), Field('COLUMN'))

print db(db.table1.COLUMN != db.table1.column).select()

[web2py] Tables defined in module not showing up

[Ruud Schroen]

Hi guys,

I'm building a Blog module, which I will post here as soon as it's done.
But there's something wrong, I've defined a couple of tables in the module.

def define_tables(self):
category_tablename = self.settings.category_tablename
post_tablename = self.settings.post_tablename
link_tablename = self.settings.link_tablename
comment_tablename = self.settings.comment_tablename

self.blog_category = self.db.define_table(category_tablename,
Field("name", label=self.T("Name of the category")),
Field("slug", compute=lambda r: IS_SLUG()("%s" % 
(r["name"]))[0]),
Field("description", 'text', label=self.T('Describe what 
will be inside this category'))
)

self.blog_post = self.db.define_table(post_tablename,
Field("title", label=self.T("Name the title of this post")),
Field("slug", compute=lambda r: IS_SLUG()("%s" % 
(r["title"]))[0]),
Field('body', 'text', label=self.T('The content of this 
post')),
self.auth.signature
)

self.post_category_link = self.db.define_table(link_tablename,
Field('post_id', 'reference %s' % post_tablename),
Field('category_id', 'reference %s' % category_tablename),
Field('is_active', 'boolean', default=True)
)

self.blog_comment = self.db.define_table(comment_tablename,
Field('post_id', 'reference %s' % post_tablename),
Field('parent_comment', 'reference %s' % comment_tablename),
Field('author', label=self.T('Your name')),
Field('body', 'text', label=self.T('Your comment')),
)

#Creates an admin role if there is none
if self.db(self.db.auth_group.role == 'admin').count() == 0:
self.db.auth_group.insert(role='admin')

#Virtual field which keeps track of the category links of each post
#Allows for an easy way of showing the post's categories in the 
views
self.blog_post.categories = Field.Virtual('categories', lambda row: 
self.category_field(row))

The tables ARE created because when I do "self.db.tables()", this is my 
output:
auth_userauth_groupauth_membershipauth_permissionauth_eventauth_cas
blog_categoryblog_postpost_to_categoryblog_comment

However.. the tables do not show up in appadmin, why?

Nevermind, it was because I initialized my module in a controller and not a 
model.

Re: [web2py] Getting more rows from a table without jQuery, PHP, etc

[Michele Comitini]

Remove PHP from the landscape and put web2py there.
You can use any AJAX enabled grid that does what you need.
Write a controller that gets called by the grid and sends JSON encoded rows
back to the grid, when the scroll to the end event is generated on the grid.

For instance you can bind a call to the web2py controller to the onScroll
event

[web2py] Can not import copy_reg

[Richard]

Hi,

I have an issue with adjusting the auth tables resulting in a custom import 
and an error that copy_reg can not be imported.

The error trace is:

Traceback (most recent call last):

I can import copy_reg from the python prompt and adding the import copy reg 
from Dal.py (suggested in a thread by Massimo) has no effect.

I use Python 2.7.8.

Any clu would be helpfull.

Copy reg is a python module. Can you import it from the normal python shell?

Re: [web2py] Re: SQLFORM grid process not working

[Anthony]

Sorry, forgot that you have to extract the form from the grid object. You 
can also get the create and update forms via:

form = grid.element('.web2py_form')

Note, that will be None if there is no form (e.g., when loading just the 
grid), so first test that it exists.

[web2py] Re: Display registration error for auth.register_bare()

[Mark Li]

Hey Massimo! Just for clarification, are you referring to opening a ticket 
for:

1. auth.register() only showing a flash msg on registration error, without 
a page reload

OR

2. auth.register_bare() returning error msg on registration fail, instead 
of just False


In my case I would like functionality for #1, but I just wanted to know to 
which of my suggestions you were referring to.

[web2py] Opening PDF files in web browser

[José Eloy]

Hello!

I've developed an application that allows users to upload document files 
(doc, pdf, xls) and then download them. The problem is when the user wants 
download the files the web browser always opens a window to ask where to 
download them (or the file is downloaded in the download folder). In the 
case of doc and xls files is fine, but would it be possible that the pdf 
files will open directly in the web browser?. To upload/download the files 
I use the standard way of web2py. This problem occurs with Firefox, Safari, 
Chrome, IE 10. The version of web2py I use with the application is the 
1.99.7.

I hope you can understand me, my english is not very good.

Thanks ins advanced.

Regards

José Eloy Torres

You need to change your download for PDFs controller, this would work if 
you don't use uploadseparate (which I usually do) :

def download_pdf():
  filename=request.args[0]
  path=os.path.join(request.folder,'uploads', filename)
  response.headers['ContentType'] ="application/pdf"
  response.headers['Content-Disposition']="inline; filename.pdf"  
+filename
  return response.stream(open(filename), chunk_size=65536)

[web2py] Re: SQLFORM doesn't have SELECT element values

[Frank Buibish]

I just checked what was being sent via POST, and it's not submitting an 
empty variable corresponding with the select name.  Now could this be 
because the select tag isn't an input tag?  I'm not an html pro yet, so 
small details like this are something i will learn with time.  Any 
suggestions on workarounds?  Should I have a hidden input field that stores 
what is in the select field? or should I use a different form inside of a 
form (not even sure that is possible).

Thanks for any suggestions

Frank

This website is hosted by PythonAnywhere, an online hosting environment.

If this is your PythonAnywhere-hosted site, and you just reloaded it, then 
the problem might simply be that it hasn't loaded up yet. Try refreshing

If you keep getting this message, you should check your site's server and

[web2py] Re: SQLFORM doesn't have SELECT element values

[Cliff Kachinske]

The Chrome developer tools should show the dragged-to select being 
populated as you drag things across.

If things aren't moving look in the "console" tab for errors. 

Also you can insert alert statements into the javascript to see if the 
events are firing.

[web2py] on_define example to improve the book: please help.

[Tim Richardson]

I'm trying to improve ch 6 in the book, DAL. 
The on_define parameter to define_table is not documented. 

This is my current text, but the example concerns me because it seems 
redundant to me. That is, until I found the example, I thought that adding 
such simple requires settings via Field definitions would still leave the 
table lazily defined.  

on_define

on_define is a callback triggered when a lazy_table is instantiated, 
although it is called anyway if the table is not lazy. This allows dynamic 
changes to the table without losing the advantages of delayed instantiation.

Example:

 db = DAL(lazy_tables=True) 
 db.define_table('person',Field('name'),Field('age','integer'), 
on_define=lambda table: [ 
table.name.set_attributes(requires=IS_NOT_EMPTY(),default=''), 

table.age.set_attributes(requires=IS_INT_IN_RANGE(0,120),default=30),

[web2py] Re: on_define example to improve the book: please help.

[Anthony]

I think you're right -- those attributes shouldn't trigger the lazy 
definition. on_define would be more useful in case something expensive is 
happening in defining one of the attributes. Also, if you define an 
IS_IN_DB or IS_NOT_IN_DB that has a Set object as the first argument (as 
the query will involve doing something like db.sometable.somefield == 
some_value, which would cause sometable to be defined).

thanks, I will amend my PR..

not sure, if lazy_tables = True is mandatory or not, another example for 
on_define :
e.g.
def on_define_bank(table): 
# default
table.name.default = ''
table.age.default = 30
# label
table.name.label = T('Name')
table.age.label = T('Age')
# notnull
table.name.notnull = True
table.age.notnull = True
# required
table.name.required = True
table.age.required = True
# requires
table.name.requires = IS_NOT_EMPTY()
table.age.requires = IS_INT_IN_RANGE(0, 120)

db.define_table('person', 
Field('name'), 
Field('age', 'integer'), 
on_define = on_define_bank)

best regards,
stifan

I believe that on_define is always done at table instantiation, so for non
lazy tables it's done when the request is executed as part of setting up
the table. so lazy_tables is not mandatory.

[web2py] Re: Bootstrap is really killing web2py

Hello Moustafa.

I agree with you and hope that we'll have soon a fully Bootstrap 3 web2py 
version.
