[web2py] Re: pagination issue redirecting to the current page
Put information about the current page in the request.args dictionary. You
could use the session, but if your user opens a second browser window it
becomes difficult to keep track of which session data corresponds to which
browser tab.

I am working on an app where the user can select items by clicking on a

item selected the user has to be redirected to index and ends up on the top

to find whatever page they were on before when they made the last
selection. How can I fix this so when the user selects the item, he is
redirected to the same page?

[web2py] Re: second page to be accessed only from first page
I believe the book is correct. Are you sure the redirect doesn't work?
request.function should be second if that was the requested function. The
redirect occurs after the request is parsed.

[web2py] Re: Query of two dates sql server
The online manual explains it here:

If I recall correctly, it may also be necessary to make an entry in your

Field('fecha', 'datetime', requires=[IS_NOT_EMPTY(),

but I get error, Is it necessary to convert the variables desde and
hasta to datetime? How can I convert them?
I've checked the SQL Server datetime format, the datetime is saved in the
records using the following format: %Y-%d-%m %H:%M:%S. I live in Mexico,
the format we use is: %d/%m/%Y %H:%M:%S
My english is not very good, I hope you can understand me.

[web2py] In views: using globals().get('somevalue') vs response.somevalue in views
In views we might use code something like this

{{if bar:}}

Got bar!
/div
{{pass}}
Why not just use the response instead?
{{if response.foo:}}
div
Got foo!

{{pass}}

On Friday, November 7, 2014 9:47:11 AM UTC-5, Anthony wrote:
For a more intuitive understanding of this behavior, consider that HTML
comments are not excluded from the actual HTML markup -- they are merely
instructions to the browser to ignore what's inside the comment (i.e.,
don't attempt to render it). The web2py template system generates HTML
markup (among other things), and because an HTML comment is intended to be
generated as part of the markup, there is no reason for the template system
to ignore it. In fact, in some cases you may even need to execute template
code inside a comment (e.g., it used to be common to wrap Javascript code
inside an HTML comment tag to accommodate older browsers), so it would not
be desirable for the template code inside HTML comments to be ignored.

[web2py] Re: Javascript in web2py view
First thing, read up on the ajax functionality in Web2py. It's way simpler
than jQuery ajax and will work just fine for what you want to do.l
Consider using the :eval target in Web2py ajax. It will allow you to send
JavaScript snippets back to the server. That way you can do things like
this on the server side:
Function get_config_details():
try:
# Your code goes here
return $('#resultip').html(data);
except:
return $('.flash').text('Server has experienced an error. Please
refresh the page.');
Also:
What does the url going back to the server look like?
It should be something like http://localhost/application/controller/function
Use the network tab in Firebug or Chrome developer tools to watch the
conversation between browser and host.
Your JavaScript looks OK to me except I'm suspicious about that url. Or
maybe your Web2py code is raising an exception.

Not entirely sure if the record representation technique will work, but

I think the css will be the hard part.
maybe you could subclass SQLFORM. If I recall correctly, there are just a

users = SQLFORM.grid(db.users,fields=[db.users.id, db.users.first_name,

headers={'users.id':'id','users.first_name':'Nombre',
'users.last_name':'Apellido'},
sortable=False, deletable=False, editable=False, create=False,

Which results into this:

[web2py] Re: Strange but useful THEAD trick!
Are you sure that's a feature and not a bug?

I often use the web2py helpers to build my tables on the fly. I've always
thought it was strange that my THEAD() helper seemed to prefer wrapping its
components inside a TD element instead of a TH. I mean, why not a TH? We
already know its in a header.
Playing around, I found this pattern works perfectly to wrap its members
in TH instead of TD:
THEAD( [ ('head1', 'head2', etc...) ] )
So if I create a TUPLE (not a list), wrap it in a LIST, and then hand it
to THEAD, it creates TH elements inside the THEAD. Every other
construction I've tried returns TD inside instead.

[web2py] map weirdness
Does anyone have a clue why this code
def make_option(row):
return OPTION(row[1], _value=row[0])
q = '''
SELECT id, name
FROM products
WHERE
is_active = 'T' AND
tenant_link = {} AND
is_container
ORDER BY name
'''.format(self.tenant_link)
rows = self.db.executesql(q)
myselect = SELECT(
OPTION('Choose'),
map(make_option, rows),
_id='container_selector',
_name='container_selector',
)
print XML(myselect)
Would produce this result. Line breaks added for clarity. Comes out the
same if not pushed through XML().
select id=container_selector name=container_selector
option value=ChooseChoose/option
option value=[lt;gluon.html.OPTION object at 0x7fa4bcfc1a50gt;,

As long as there are gluon.html and gluon.sqlhtml you can continue as

My proposal is the following:
1) deprecate SQLFORM (but keep it for backward compatibility)
2) replace
form = SQLFORM(table).process()
...
{{=form}}
with
form = JForm(table)
...
{{=form}}
what is the difference? SQLFORM generates html. JForm generates JSON
metadata which is then converted into the form client-side by the js in
jform.js.
why?
- it is much faster because all rendering is done client-side
- it can optionally submit the form via Ajax without having to change
your
code.
- it is much easier to style and create widgets for different css
frameworks.
For example include the right one:
static/js/jform-bootstrap2.js
static/js/jform-bootstrap3.js (I only provide a layout for bs2 and not
bs3)
- it is much more powerful because you can customize widgets in JS.
We could also add a JTable, a JMenu and a JLogin and keep all the
styling
info in JS files as opposed to Python files.
This would make web2py leaner and cleaner.
Thoughts?

[web2py] Re: two forms submitted into the same cotroller
Here is what I do. Your page should have one form only. Make 2 divs. Top div has your fixed fields including the one that triggers the variable content. Use jquery to catch the change event for the field. When the field changes send an Ajax request to the server. Let the server build the variable form and return it to the server to populate the second div. I build the individual form elements rather than using FORM or SQLFORM. That way I avoid form within a form problems. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: one-to-many relations and form for crerate records
Here is what I would do.
On the client have a var contact_count = 0
All of your starting contact fields will have a suffix __0
When the user clicks the add contact button, use Javascript to increment
the contact_count and write another set of contact fields. This time set
the suffix to __1
Increment the number in the suffix accordingly each time the user clicks
the add contact button.
Use form submission as usual.
In the controller you can link the sets of contact fields together by the
suffix number.

Hello.
This is just a simple example, my actual model is more complex, but I
think I can explain the main idea.
Model:
db.define_table('users',
Field('name', 'string'))
db.define_table('contacts',
Field('user', db.users),
Field('phone', 'string'))
Well, each user can have from 1 to infinite phone numbers.
I want user entering all his numbers while registering.
So, what are the ways to realize it?
1) Split registration process to steps, step one - enter name, step two -
add phones one by one. Ugly.
2) Use smartgrid. Have parent-children out of the box. Being, may be,
cool tool for admin purposes, it is absolutely unintuitive and unusable for
end-users.
3) Make custom form with jquery: form have button add another phone
number, user press the button and another text field adding dynamicaly for
the infinite form. Excellent way. But. This is theoretically. And I cant
find any practical examples.
So, testing I can see that inputs with same name processing by web2py as a
list, its fine! For example, there is a duplicated inputs in the form:
input name=phone type=text
input name=phone type=text
after submitting, I have ['123456','345678'] on form.vars.phone. Cool.
Cycle and do db.insert() voila, you say!
No.
Linked table contacts actually is more more complex. It have address
string, state string, postal, validators and another linked tables such
postals, cities, etc, etc...
And I have no idea how build my form and how to process my form vars
within controller with all contact table validators?
Is there any elegant way doing this?

You may have to mess around with the css a bit to get the vertical

Thanks Cliff and Niphlod,
I've used ajax several times and think I understand the process. My
problem now involves using a form inside a bootstrap modal and using ajax
to submit the form. What I meant by web2py intercepting the event was
that web2py.js registers an event handler for the submit which interferes
with the modal submit handler. web2py.js adds the 'disabled' class but
does not detect the succesful ajax response and then remove the class.
Per Niphlod's request, I've recreated the problem using a minimum of code
that I've pasted below. This codes works if I remove web2py.js and fails
if I leave it. To recreate, click the button to open the model and then
click submit on the modal. You can see the button becomes disabled (even
if you close and reopen it remains disabled). In other testing, I also had
web2py add 'display='none' ' to the target but the code below doesn't do
that.

It doesn't matter whether it's JQuery's ajax or Web2py's ajax. The syntax

In that response you would include, assuming JQuery has been loaded on
the page, something like
$('#somentity_on_page').whatever_attribute_needs_changing('new state of
the attribute');
Web2py isn't intercepting anything. You push a button, click a link,
whatever, the browser sends a request. The request goes to your web server,
be it Rocket, Apache, Nginx, any other. The web server sends the request to
Web2py because the server is set up that way. Web2py then processes the
request and returns a response.
Excuse me if I'm interpreting incorrectly, but your questions suggest a
certain misunderstanding about what's going on. Chapters 1, 3 and 4 of the
Web2py manual provide a pretty good overview of how this all works. If I
recall correctly, Wikipedia has some reasonably good articles about http,
http requests and http responses.

I've found a workaround, the last line in JQPlot.xml was:
return current.response.render('jqplot.html', d)
so I can add script html tags to the template jqplot.html:
script src=/karakolas/static/jqplot/jquery.jqplot.min.js/script
script src=/karakolas/static/jqplot/jquery.jqplot.min.css/script
but I'm sure it can be done better...

[web2py] Re: What is the right way to serve static files through a CDN ?
If, like me, you use the same static files on every page, just hard code
them into layout.html.
I realize this may make upgrading more, um, interesting, but it's much
simpler than pattern-based routing.

I am using a CDN and am trying to configure web2py to use it instead of

So far I've been using pattern-based routes like this :
cdn = 'https://xxx.cloudfront.net'
routes_in = (...
('/static/$anything', cdn + '/static/$anything'),
...
)
routes_out = (...
('/static/$anything', cdn + '/static/$anything'),
...
)
This basically works, but this has to be implemented on a pattern-based
routes.py which means I lose many cool features like map_hyphen,
default_application, default_controller mappings...
Is there a way to use a CDN with a parametric router ?
I read somewhere that the host parameter in URL can also be used to setup
a CDN, but it seems a bit tedious to find all URL and rewrite them.
Isn't there a variable in gluon.rewrite that I can mess with to trick
web2py into serving CDN-based content ?

[web2py] Re: Hypermedia API and Collection+JSON in web2py
Massimo,
The new recipe you propose is bottle+dal+validators+auth+collection
Could it be bottle+whatever_you_like+validators+auth+collection?
I have found myself needing to execute complex SQL queries. In this
situation, in my opinion, psycopg2 would serve me just as well as dal.
On Sunday, June 22, 2014 4:45:06 PM UTC-4, Massimo Di Pierro wrote:
I added Hypermedia API support to web2py using Collection+JSON.
Experimental.
Collection+JSON is a standard for self documenting RESTful API.
Read more: http://amundsen.com/media-types/collection/
Example
=
Let's say you have a model:
db.define_table('thing',Field('name'))
and in controller default.py you add
def api():
from gluon.contrib.hypermedia import Collection
rules = {
'thing': {
'GET':{'query':None,'fields':['id', 'name']},
'POST':{'query':None,'fields':['name']},
'PUT':{'query':None,'fields':['name']},
'DELETE':{'query':None},
}}
return Collection(db).process(request,response,rules)
And now by magic your table thing is fully exposed using the
Collection+JSON API. The API is self documenting and supports GET, POST,
PUT, DELETE, etc.
For example you can do things like:
curl http://127.0.0.1:8000/app/default/api/thing
curl http://127.0.0.1:8000/app/default/api/thing/1
curl http://127.0.0.1:8000/app/default/api/thing?id=1
curl
http://127.0.0.1:8000/app/default/api/thing?name=Boxid.gt=10_offest=10_limit=30
curl -X POST -d name=Box http://127.0.0.1:8000/app/default/api/thing
curl -X PUT -d name=Chair http://127.0.0.1:8000/app/default/api/thing
?name=Box
curl -X DELETE
http://127.0.0.1:8000/super/collections/conform/thing?name=Chair
The API are completely self documenting as explained here
http://amundsen.com/media-types/collection/
It is customizable
==
rules = {
'thing': {
'GET':{'query':None,'fields':['id', 'name']},
'POST':{'query':None,'fields':['name']},
'PUT':{'query':None,'fields':['name']},
'DELETE':{'query':None},
}}
Let you specify which tables are exposed, which methods are available and
which fields are exposed for each method. The query property lets you
specify optional filters for example {
'query':db.thing.name.startswith('A'),} will only exposed things
starting with letter A. Fields can be conditional and different for
different users or for the same user in different stages of a workflow (the
communication is stateless, but the server is not).
Supports complex queries
=
http:/./{table}
http:/./{table}/{id}
http:/./{table}?{field}=value
http:/./{table}?{field}.gt=value # fieldvalue
http:/./{table}?{field}.le=value # field=value
...
http:/./{table}?_orderby={field}
http:/./{table}?_limitby=value
http:/./{table}?_offset=value
...
and combinations there of. They are mapped directly into DAL queries. More
examples are in the API response itself.
The bigger picture
===
This API provide enough information to generate forms and tables and grid
completely client side. Recently we stumbled against the problem of moving
from Bootstrap 2 to Bootstrap 3 because so much of the form and grid logic
is server side. My plan is to move most of the logic in the JS library and
allow users to customize them for different CSS frameworks.
Eventually (in dreams) I would like to have a very slim framework based on
bottle+dal+validators+auth+collection and have client side only templates
(based on jquery, sugar, and ractive.js) that can generate forms and grids
based the collection API. This framework could ship with web2py and allow
you to program using same web interface that we all love. There are many
design decisions to make to get there. Your suggestions are welcome.
How can you help?
===
1) test it.
2) there are many existing client side tools for Collection+JSON. Try them
with web2py.
3) blog about it and suggest improvements.
I said, it is experimental
===
Collection+JSON has limits:
- it is very verbose JSON. This is my my implementation has compact=True
option that breaks the protocol but makes much smaller JSON messages.
- it does not convey field type information and constraints. This is why I
extended to do so but more work is needed because DAL types do not map into
HTML5 input types (this of list:string or list:reference).
More extensions of the protocol are required. Extensions are allowed. Yet
they may change the API in the near future.

How can I protect against this and enforce the update of the right
record?
Thank you.

[web2py] Re: Web2py With Pycharm project on remote Server
I agree with Massimo. Unless your situation forbids it, the simplest thing would be to code on your local workstation and push code to the server with git or whatever version control system is in use. If there's no version control system on the server you can even use rsync. But you should use git on your workstation so you can roll back changes if necessary.

[web2py] ajax posts text input twice when name and id are identical
This is not supposed to happen and I don't know why it did.
The js looks like this:
$('#products_on_order').on('click', '.edit_bound_container', function(e){
//alert(this.id);
var container_id = this.id.split('__')[1]
var count_field = 'bound_container_count_edit__' + container_id
var pounds_field = 'bound_container_quantity_packed_edit__' +
container_id
ajax(
edit_bound_container_url,

that I could find.
Changing the input id so that it is not identical to the input name made
the problem go away.

[web2py] Re: ajax posts text input twice when name and id are identical
I can do that.
But I discovered it was doing something much more interesting than my
original diagnosis.
The inputs in question were editable and generated by the controller. As
such they had an assigned value. When I ajaxed them to the server,
apparently two copies of the input were sent. One copy had the original
value and the other had the edited value.
If I would do something like alert($('#the_field').val()); it would alert
the edited value. So the final work around was to park those values in
hidden fields and send those across via ajax. Of course that doesn't answer
why it was happening. And that fixed the problem. I don't know why I
thought the other work around fixed it unless it was post-lunch fog.
But yes, I will put up the html and the post stream later today.

[web2py] Re: {{=XML(row.contents, sanitize=True)}} and em/em
You can tune the tags and attributes that XML will allow.
XML has a parameter called permitted_tags. It is a list of tags that XML
will not escape.
You could, at the top of your controller, create your own list of permitted
tags. Then call XML like this:
XML(row.contents, sanitize=True, permitted_tags=permitted_tags)
This is what the permitted_tags parameter looks like with the added entry
for em. You can find it in gluon/html.py around line 1536.
permitted_tags=[
'a',
'b',
'blockquote',
'br/',
'i',
'li',
'ol',
'ul',
'p',
'cite',
'code',
'pre',
'img/',
'h1', 'h2', 'h3', 'h4', 'h5', 'h6',
'table', 'tr', 'td', 'div',
'strong','span',
# entry below added
'em'
],
If you look at the XML class in html.py you will see another parameter
called allowed_attributes. I suppose you could make your own dictionary
to allow a style attribute for some html tags and pass it in when you call
XML.

[web2py] Re: Hypermedia API and Collection+JSON in web2py
Massimo,
I like the way your thoughts are headed.
doesn't the many2many issue goes away if one uses, for example, MongoDB?
On Sunday, June 22, 2014 4:45:06 PM UTC-4, Massimo Di Pierro wrote:
I added Hypermedia API support to web2py using Collection+JSON.
Experimental.
Collection+JSON is a standard for self documenting RESTful API.
Read more: http://amundsen.com/media-types/collection/
Example
=
Let's say you have a model:
db.define_table('thing',Field('name'))
and in controller default.py you add
def api():
from gluon.contrib.hypermedia import Collection
rules = {
'thing': {
'GET':{'query':None,'fields':['id', 'name']},
'POST':{'query':None,'fields':['name']},
'PUT':{'query':None,'fields':['name']},
'DELETE':{'query':None},
}}
return Collection(db).process(request,response,rules)
And now by magic your table thing is fully exposed using the
Collection+JSON API. The API is self documenting and supports GET, POST,
PUT, DELETE, etc.
For example you can do things like:
curl http://127.0.0.1:8000/app/default/api/thing
curl http://127.0.0.1:8000/app/default/api/thing/1
curl http://127.0.0.1:8000/app/default/api/thing?id=1
curl
http://127.0.0.1:8000/app/default/api/thing?name=Boxid.gt=10_offest=10_limit=30
curl -X POST -d name=Box http://127.0.0.1:8000/app/default/api/thing
curl -X PUT -d name=Chair http://127.0.0.1:8000/app/default/api/thing
?name=Box
curl -X DELETE
http://127.0.0.1:8000/super/collections/conform/thing?name=Chair
The API are completely self documenting as explained here
http://amundsen.com/media-types/collection/
It is customizable
==
rules = {
'thing': {
'GET':{'query':None,'fields':['id', 'name']},
'POST':{'query':None,'fields':['name']},
'PUT':{'query':None,'fields':['name']},
'DELETE':{'query':None},
}}
Let you specify which tables are exposed, which methods are available and
which fields are exposed for each method. The query property lets you
specify optional filters for example {
'query':db.thing.name.startswith('A'),} will only exposed things
starting with letter A. Fields can be conditional and different for
different users or for the same user in different stages of a workflow (the
communication is stateless, but the server is not).
Supports complex queries
=
http:/./{table}
http:/./{table}/{id}
http:/./{table}?{field}=value
http:/./{table}?{field}.gt=value # fieldvalue
http:/./{table}?{field}.le=value # field=value
...
http:/./{table}?_orderby={field}
http:/./{table}?_limitby=value
http:/./{table}?_offset=value
...
and combinations there of. They are mapped directly into DAL queries. More
examples are in the API response itself.
The bigger picture
===
This API provide enough information to generate forms and tables and grid
completely client side. Recently we stumbled against the problem of moving
from Bootstrap 2 to Bootstrap 3 because so much of the form and grid logic
is server side. My plan is to move most of the logic in the JS library and
allow users to customize them for different CSS frameworks.
Eventually (in dreams) I would like to have a very slim framework based on
bottle+dal+validators+auth+collection and have client side only templates
(based on jquery, sugar, and ractive.js) that can generate forms and grids
based the collection API. This framework could ship with web2py and allow
you to program using same web interface that we all love. There are many
design decisions to make to get there. Your suggestions are welcome.
How can you help?
===
1) test it.
2) there are many existing client side tools for Collection+JSON. Try them
with web2py.
3) blog about it and suggest improvements.
I said, it is experimental
===
Collection+JSON has limits:
- it is very verbose JSON. This is my my implementation has compact=True
option that breaks the protocol but makes much smaller JSON messages.
- it does not convey field type information and constraints. This is why I
extended to do so but more work is needed because DAL types do not map into
HTML5 input types (this of list:string or list:reference).
More extensions of the protocol are required. Extensions are allowed. Yet
they may change the API in the near future.

I've had a quick read of the web2py book but I was a little surprised by the emphasis on self-submission/postbacks, it's not a technique that I would choose myself. I was wondering whether there was anything in python or web2py that make this technique particularly appropriate ? Being new to python etc. I thought it worthwhile asking. The application that I have in mind has a number of one to many and a few many to many relationships and in a number of cases I will want to use a combined form with both the 'one' and one or some of the 'many' (perhaps on a tabbed layout, or scrollable perhaps) almost certainly using Ajax to deal with the different parts of the page. It is interesting to look at the different frameworks and see the different emphasis that each one has, and to see if that does have far-reaching consequences, it's worthwhile spending a little time to try to make the right choice. thanks graham -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: Need to have def 4() and def dir() to 301 redirect. Is it possible?
You probably need to use the URL rewrite facility. Read here for
information about it:
http://web2py.com/books/default/chapter/29/04/the-core#URL-rewrite
Once your request gets to the web2py router, it will be parsed as follows:
www.mydomain.com/web2py_application/controller/function/args(0)/..args(n)?vars
So in the case of www.mydomain.com/4, the router will attempt to route your
request to an app named 4. In the second case it will look for an app
named dir.
URL rewrite avoids this because it happens before the Web2py router gets
called.

The above shouldn't produce an error, but the following will:
foo = 'bar'
def main():
print foo
foo = 'foo'
In the above, the assignment to foo indicates foo is a local variable
(since it hasn't been explicitly declared as global), so the previous print
statement raises an exception because it refers to a local variable that
has not yet been declared.
In your original example, because there is no assignment to foo within the
function, the foo in the print statement is assumed to be global, and there
is no exception because foo is in fact a global variable.

Because you have not explicitly declared i_am_global as a global variable, it is automatically defined as being local to the main() function. Therefore, any earlier references to i_am_global (e.g., line 45) will generate an UnboundLocalError. In Python, you can always read a global variable without declaring it to be global, but if you want to create or overwrite a global variable within a function, you must first declare it to be global.

Because if your statement is true, we could eliminate some pretty hairy

res = mytable.find()
.
return dict()
And of course it works.
But is it fast to connect/disconnect every time in function? What's about
connection pool?
I consider connection pool could increase access to database.
1. Actually I would like to ask how to access to database without DAL but
at maximum speed?
2. Do I need connection pool for fast database access? (I think, yes.)
3. How could I build custom connection pool for database access without

To expand a little on Massimo's explanation. Find the reference to Cooperating Applications in the online manual. Once you have figured out which app will be the master app, you can put all the model files in the master apps models directory, then softlink the files you need in other directories.

The Field looks like this:
Field('score', 'decimal(4,3)')
It does work to convert to string such as:
{{=str(t.score)}}
but neither does this work:
{{=float(str(t.score))}} # error: type 'exceptions.ValueError' could
not convert string to float: None
and nor this:
{{=float(t.score)}} # error: type 'exceptions.TypeError' float()
argument must be a string or a number
I even tried to import decimal and calculate that with t.score, but even
that didn't work! What's going on?

[web2py] Re: Best practice for a development environment together with a live environment
I have used rsync to update models, controllers, views, modules and so on. For database updates I create a separate script and test, test, test it. I don't use the DAL. Sometimes I write SQL, sometimes python using the database driver. Going forward it will probably just be SQL. On a production box you have migration set to false for all models, yes? So the process for migrating the database is: 1. Shut down the app. 2. Run your migration script. 3. Set fake_migrate = True 4. Restart the app and force fake migration on all changed tables. You can do this by opening the tables in the appadmin application or though the user interface. All you need to do is ensure you can select records out of the tables. 5. Turn all migration off Don't know if this qualifies as a best practice, but it's what I do. Also on my development box I run the same DB backend as on production. This helps eliminate surprises. On Monday, February 10, 2014 6:54:10 AM UTC-5, Robin Manoli wrote: Hey, I'm working on developing projects that will have live releases. In other words, I want to be able to develop my app calmly on a dev version, and once I'm done with that I want to synchronize it with the live version which is open to the public. I'm using two separate mysql databases for this, because I don't want to fill the live one up with garbage. The easiest way I've found is to have two different applications (one live and one dev), and to synchronize them by using rsync on linux. It is quite scary though when it comes to alter the db tables. It has happened that the live app completely breaks because of a very simple change (a change of name of a table column). I wonder how you guys encounter this situation. Do you recommend using git? Is it even possible to use git, since web2py so easily gets confused with how the database looks? It would be nice with some tutorial on this, because I have not yet learnt git or similar things. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: Multiple SOLIDFORMs from table rows
Have you tried it without the showid arg?
On Monday, February 10, 2014 3:12:36 AM UTC-5, Mike Constabel wrote:
Hi,
I try to generate multiple SOLIDFORMS from table rows.
Simple example in pseudo code:
x = db(y.z).select()
for d in x:
form=CAT(form, SOLIDFORM(d))
return dict(form=form)
This works for me:
Model:
#simplified, the tables are much longer in real
db.define_table(foo_analysis_type,
Field(uuid, length=64, default=lambda:str(uuid.uuid4())),
Field(analysis_code, integer, label=T(analysis_code),
requires=IS_INT_IN_RANGE(0,)))
db.define_table(foo_analysis,
Field(uuid, length=64, default=lambda:str(uuid.uuid4())),
Field(customer_uuid, length=64, label=T(customer_uuid),
requires=IS_IN_DB(db, 'icp_customer.uuid', db.foo_customer._format,
multiple=False)),
Field(analysis_type_uuid, length=64,
label=T(analysis_type_uuid), requires=IS_IN_DB(db,
'foo_analysis_type.uuid', db.foo_analysis_type._format, multiple=False)),
Field(order_number, integer, label=T(order_number),
requires=IS_INT_IN_RANGE(0,)))
Controller:
fields3 = [['order_number', None]]
form3 = P()
analysis = db(db.foo_analysis.customer_uuid ==
request.get_vars.uuid).select()
for a in analysis:
form3 = CAT(form3, SOLIDFORM(db.foo_analysis, a, fields=fields3,
showid=False, readonly=True), P())
return dict(form3=form3)
For every table row i got a nice form.
But I need left outer joins. And there I stuck.
Same Model as above, Controller:
fields3 = [['order_number', 'analysis_code']]
form3 = P()
analysis = db(db.foo_analysis.customer_uuid ==
request.get_vars.uuid).select(db.foo_analysis.ALL,
db.foo_analysis_type.ALL,
left=db.foo_analysis_type.on(db.foo_analysis.analysis_type_uuid==db.foo_analysis_type.uuid)
)
for a in analysis:
#form3 = CAT(form3, a) this works, it prints rows with all
data, so the select is ok?
form3 = CAT(form3, SOLIDFORM(db.foo_analysis, a, fields=fields3,
showid=True, readonly=True), P())
return dict(form3=form3)
Here I got
type 'exceptions.AttributeError'('Row' object has no attribute 'id')
I tried many other combinations of fields, forms, selects, but
got every time errors.
It would be really great if I can get a hint howto correct code
this.
Regards,
Mike
