[Joe Magaro]

Thanks Annet: I am aware of web2py URL helpers. I use them inside of my 
views.

However in this case, they wont work for me as the data is stored in a 
table and output to a web page, I require another method.

[web2py] Cant install via git repo

Hi, on my web2py install I tried to install some applications via a git

Any idea what is causing this?

[web2py] Web2py: Using images in HTML data

[Joe Magaro]

Hello,

I have an application that uses a rich textbox to insert images into a 
field saved in a table.

So for the image URL, I would have to put 
"/MySiteName/static/images/image.gif" as an example, then save to the 
database.

I really don't like hardcoding the site name, if I copy the project to a 
new one (as I often do) I need to scrub the database and change all entries 
to match.

Is there a way around this?

[web2py] Web2py admin crashes

[Joe Magaro]

Hi, 

All was working well, until today I went and clicked "administrative 
interface" for my site, and it issues a ticket.

Internal errorTicket issued: 
admin/65.94.212.187.2013-10-03.19-26-12.8b8b3b98-0858-4925-a517-59ebed5f1ad1

When I click to view the ticket, it crashes and issues another ticket. I 
checked the http logs, but cant seem to find anything of importance. Can 
some one give me the next step to help solve this issue?

Hi. I have another issue,and in researching it i'm wondering if this is

Hi Mossimo - Where would I look for this? I haven't done sessions in my 
apps yet, but maybe one of the projects I loaded might have. Also, why 
would an app affect the admin site?

[web2py] Re: Using a python module in web2py

[Joe Magaro]

Well, I didn't know I needed to restart Apache.

Now I get a different error. I did the nltk download in python, but do I 
need to do something in web2py?

  Resource 'corpora/wordnet' not found.  Please use the NLTK
  Downloader to obtain the resource: >>> nltk.download().
  Searched in:
- '/var/www/nltk_data'
- '/usr/share/nltk_data'
- '/usr/local/share/nltk_data'
- '/usr/lib/nltk_data'

- '/usr/local/lib/nltk_data'

[web2py] Re: Web2py Grid: Hiding from the main grid but show on other views

[Joe Magaro]

Hi Massimo.

Perhaps I explained this incorrectly.

When I added db.CodeMaster.Code_Example.readable = False that did two 
things:
a) Removed the Code_Example Field from the Grid (good!)
b) Removed the Code_Example Field from the display view. (Not what I want)

(a) is what I want, but I when I display the record, I need the field 
output on (b) the display view.  Is it possible to do this using the grid?

[web2py] Web2py Grid: Hiding from the main grid but show on other views

[Joe Magaro]

Hi, I am just learning web2py and I have a working grid: 
form=SQLFORM.grid(db.CodeMaster,editable=auth.has_membership('Editor_Group'), 
create=auth.has_membership('Editor_Group'),deletable=auth.has_membership('Editor_Group')
)
 
There is a field in db.CodeMaster that I would like to hide from the grid 
view, but have it shown in other views.
 
I tried db.CodeMaster.Code_Example.readable = False
 
That seemed to work except it removed it from all views except edit.
 
Any help is appreciated!
