[Hobo Users] Custom links on items in table-plus

[Patrick Fitzgerald]

Sorry for posting this under:

Prototype v.1.6.1 and Hobo

Hi All,

  Scratching my head over this one.  I have created a table using:

<table-plus fields="status, created_date, updated_date, file_path_link, user" />

Which display everything in a lovely table.  The thing is, file_path_link contains text which has the location of a file on the filesystem.  I want to make this a hyper link and cannot get it to work.

For example, if the text returned by file_path_link is: 1/2/filename.jpg

How do I make that a hyper link which points to:

http://127.0.0.1:3000/1/2/filename.jpg

The idea is that clicking on the text will allow the user to download the file.

All help and suggestions welcome!

Thanks,

Patrick

Did you not get my response? Cutting and pasting...


It should be something like:

<file-path-link-view:>
<a href="http://127.0.0.1:3000/#{this.to_s}" />
<file-path-link-view:>

If 127.0.0.1:3000 is the rails server, you should use #{root_path}
instead of hardcoding in the url.

cheers,
Bryan

Hi Bryan

     I got your response just after I resent this!  I managed to get it working using your advice.  What I was missing was the magic provided by the "this" object.  Pretty basic error!

To get it to work I used a parameterized version of collection.  

In the definition for index-page in application.dryml I used:

<collection param/>

Then I created an index.dryml in the view for my controller:

<index-page>

<collection: replace>

<div>

<table-plus fields= "status, created_date, updated_date" >

<controls:>

<% if this.capture_path =~ /File not available/ %>

No file

<% else %>

<a href="#{this.file_path}" >Download file</a>

<% end %>

</controls:>

</table-plus>

</div>

</collection:>

</index-page>

The key to getting all this to work was remembering the "this" object!

I hope this helps someone else with a similar problem.  

Thanks Bryan for the push in the right direction.

Cheers,

Patrick
