I've implemented django-pagination in my app to take care of pagination, and it's all good. The one thing I can't figure out is how to allow users to choose a certain value for the records per page e.g. 15, 30, 45, 60, 100 or all records.
What's the correct way to go about this?
When you construct a Paginator, you pass in the number of records per page. You need to get this value from the user, store it, and pass it in.
For example, it could be a user setting -- if so, add it to your user setting Model, collect it in a form, store it, then get the Model from the db before creating the Paginator and pass it in.
Or it could just be a session variable that is set from an element on the page -- again, put the element on the page, use it to set the session variable, and pass it into the Paginator object.
Looks like it was covered in this question:
Flexible pagination in Django
EDIT: Reading the comment.
If you read the source,
http://code.google.com/p/django-pagination/source/browse/trunk/pagination/templatetags/pagination_tags.py
The tag, autopaginate takes a number or a template variable.
if isinstance(paginate_by, int):
self.paginate_by = paginate_by
else:
self.paginate_by = template.Variable(paginate_by)
So, try passing in a template variable in your view 'page_by':10 and the use {% autopaginate list page_by %} -- then you can set the page_by from the query string, db, or whatever you want.

I am creating a database that contains Product information (tblProductInfo), a list of test methods (tblTests), and the results that the product gets (tblResults).
I'm adding forms so that a user can enter the results of a previous or new product. This information will be added once all the testing for that product is done. So, I would like to be able to show a list of the tests from tblTests, and have the user enter the results in a text box of some sort displayed directly next to the tests. I can't figure out a way to do so, where it will then save all the results that the user entered.
I have created a form with a subform, where the subform shows the 2 columns (tests and results) and when I change it to allow DataEntry, it gets rid of all the test names. I need it to keep the test names displayed, but allow entry in the results column.
Any ideas?
Below is a screenshot of an example of what I would like, although I need the Results column to be empty.
Create a continuous subform with only the tblresults as the recordsource, and for the header or each field of results use the related test as the label is how I would do it. Set allow additions to yes, allow edits to no allow deletions to no.
I have a form in Lotus Notes containing an editable text field.
Once the user enters a value in that field, it gets saved properly when I check it by opening the document from the back-end.
But I need this value to be seen in the form every time the user opens the form.
Because it is a configuration form where the user should be able to see all the values saved.
For example, a field which contains the path to download a report. And it should be an editable field itself. Is there any way to do this? Any sort of clue or help would be really appreciated. Thanks in advance!
The value of an editable field stored in a document does keep it's value every time the user opens the document.
It sounds like you may ask for something else. You want User A to create a document, enter a value (i.g. a download path) and save the document. When User A or User B later creates another document based on the same form, the previously entered value should be the default. Is that what you mean?
In that case you could simply use #DbLookup or #DbColumn in the formula language in the Default Value property of the field.
Or create a lookup view with the previously created document, sorted descending by date, then use the GetFirstDocument method of the NotesView class to get the first document in that view and read the value out of it using the GetItemValues method of the NotesDocument class.
Performance tip: If you make sure the value you want to look up is visible in the lookup view you can use the GetFirstEntry method of the NotesView class, then use the ColumnValues property to get the value, this is much faster.
Solution is to use #DbColumn in the default value of the editable text field of my form
I'm interested in creating a fill-in-the-blank story generator for kids. I want to create a form where they can put in the names of characters and other things and have that data populate a pre made story. After they hit SUBMIT they would be taken to a follow up page with their input and the story in plain text. I'm pretty new to this but very eager to learn. What would be the best way to go about creating this form that generates stories?
It seems you would need two database tables - one for storing the original story templates and another one for storing the generated texts.
The challenging part with the template database is signifying the parts where there can be user input. One idea - place a special format code inside the text in the following manner:
Once upon a time, in a forest far away, lived ::00001::.
Assuming you are loading that template as it is in an element inside a form (I would avoid textfields for this purpose and just place the text).
After the text is loaded into the web page (javascript onload), replace your markers with input fields (I'd use jquery for that). You can use jquery to search an elements text/innerHtml and replace it with another html element. Here is an idea how to do that. The replacement of markers with inputs can be done in a javascript while loop, as long as there is "::" in the text of the element.
Then your ::00001:: could be replaced for example with:
< input type='text' id='input00001' name='input[00001]'/>
Then, when the user submits the form, you can get the values for each field and store them to a second database with the given ids. This way, you will be able to reload them later (same process, only instead of inputs, you would replace the codes with their corresponding values).
This way, in the second database table you only save the input values and not the whole text, to save up memory. Probably in the second table you would like to store the id of the field, the value, perhaps a template id (so that you know for which story template it corresponds) and a user id or at least a timestamp, in case you can have many generated stories for the same template.
Hope this helps!
I have a requirement, where some 14-15 fields of data have to be asked from the end user and some processing has to be done for those values.
But one of the values should be pre-filled with a drop down list of values, and user can only select one of the values in that list. Also, the user can add a suffix value to this fixed value(by fixed value i mean value in drop down list selected by end user). So this parameter when sent to the server for processing, is fixed value+suffix.
I want to know if this type of form processing can be done using bean/jsp. Or with any other method.
If you could give me a code sample for implementing this (whether bean or other method) then that would be great.
The processing that has to be done after the user submits all 14-15 values is written as java code. I should be able to invoke this code to do processing.
Of course it can be done using servlets/JSP.
You need to generate apage containing an HTML form. This form will have to contain a select element withh all the fixed options, and a text input where the user has to enter the suffix. When submitted, the servlet/JSP will have to get the submitted values from the request parameters, and do its processing.
A code sample would be too hard to give you. You need to read a whole tutorial about HTML forms, the servlet API and how JSPs work.
I have a form with two subforms, both of which are continuous. Each form has a field to accept the name of the person who created the record. Almost every time, the same person will be creating all of the records, so it would be really convenient if the fields would autofill once the main record has been set.
I've tried several approaches to this, but none seem to work quite right (e.g., the first of the continuous forms won't autofill because it came into existence alongside the main record). This is Access 2003.
OnCurrent, OnClick, etc...
If IsNull(Me.MyField) or Me.MyField = "" Then
Me.MyField = Me.Parent.MyRelatedField
End If
It may be best to set the default value of the control in the after update event for the control. This means that it will fill with whatever the previous value was.
Me.SomeText.DefaultValue= """" & Me.SomeText & """" ''Text
