    text
    copied!<p>I defined several models: Journals, volumes, volume_scanInfo etc.</p> <p>A journal can have more volumes and a volume can have more scanInfo.</p> <p>What I want to do is:</p> <ul> <li>in the admin page of journals I want to have the list of the volumes inline (done)</li> <li>connect each volume of the previous list to its admin page where I can show the form to edit the volume and the list of its "scan info" inline.</li> </ul> <p>so I want to have something like:</p> <pre><code>Journal #1 admin page [name] [publisher] [url] ..... list of volumes inline [volume 10] [..(other fields)..] &lt;a href="/link/to/volume/10"&gt;Full record&lt;/a&gt; [volume 20] [..(other fields)..] &lt;a href="/link/to/volume/20"&gt;Full record&lt;/a&gt; </code></pre> <p>Then</p> <pre><code>Volume #20 admin page [volume number] [..(other fields)...] ...... list of the scan info inline [scan info 33] [..(other fields)..] &lt;a href="/link/to/scaninfo/33"&gt;Full record&lt;/a&gt; [scan info 44] [..(other fields)..] &lt;a href="/link/to/scaninfo/44"&gt;Full record&lt;/a&gt; </code></pre> <p>What I tried to do is defining a model method that create the code and trying to use it inside the class that defines "volume inline" in the admin, but it doesn't work.</p> <p>In other words </p> <p>the model "Volume" has inside something like:</p> <pre><code>def selflink(self): return '&lt;a href="/admin/journaldb/volume/%s/"&gt;Full record&lt;/a&gt;' % self.vid selflink.allow_tags = True </code></pre> <p>and</p> <pre><code>class VolumeInline(admin.TabularInline): fields = ['volumenumber', 'selflink'] model = Volume extra = 1 </code></pre> <p>But this gives the following error:</p> <pre><code>Exception Value: 'VolumeInline.fields' refers to field 'selflink' that is missing from the form. </code></pre> <p>Any idea?</p> <p>Thanks, Giovanni</p>
