    <p>I have a list of tuples, that I get from a sqlite3 database. I have tried to get the database differently without any luck, this is not the person of this question but ultimately if it helps format the description of my radio button form I will be ecstatic.</p> <p>the list I have looks like:</p> <pre><code>images = [(1, u'True', u'file_Name.img', u'img', u'train', u'2013-02-0509:59:46.442660file.ext', u' file2.ext', u'ABC', u"[u'prod_one-prod_two']", u'name@email.com', u'nothing happens', u'2013-02-0509:59:46.442660', u"[u'ftp://link/file_Name.img', u'ftp://link/file3.ext', u'ftp://link/file_Name.log']"),(2, u'True',u'file_Name.img', u'img', u'train', u'2013-02-0509:59:46.442660file.ext', u' file2.ext', u'ABC', u"[u'prod_one-prod_two']", u'name@email.com', u'nothing happens', u'2013-02-0509:59:46.442660', u"[u'ftp://link/file_Name.img', 'ftp://link/file3.ext', u'ftp://link/file_Name.log']")] </code></pre> <p>What I would like to do is have the value of the selection be the first element of each tuple</p> <pre><code>rows = [(str(x[0]), x) for x in images] form.images.choices = rows </code></pre> <p>However it looks as if I just printed that mess with the unicode character and everything.</p> <p>So I am trying to format it in a nice table so it is easy to see what each tuple contains</p> <pre><code>descriptionList = [] description = '' for i in images: for j in i: description = description + '\t|' + str(j) descriptionList.append(description) rows = [(str(x[0]), y) for x, y in zip(images, descriptionList)] form.images.choices = rows </code></pre> <p>However it does not have the tab character in the output when I display the form.</p> <p>So now I am thinking about passing descriptionList into the template and display it beside each radio box to act as a description in the form.</p> <pre><code>return render_template('database.html', form=form, descriptions = descriptionList) {% for subfield, desc in zip(form.images, descriptions) %} &lt;tr&gt; &lt;td&gt;{{ subfield }}&lt;/td&gt; {# {{ subfield.label }} (this is a comment)#} desc &lt;br&gt; &lt;/tr&gt; {% endfor %} </code></pre> <p>However I get the error "UndefinedError: 'zip' is undefined"</p> <p>and without it I get:</p> <pre><code>{% for subfield, desc in (form.images, descriptions) %} ValueError: too many values to unpack </code></pre> <p>Any suggestions on how to solve this would be nothing short of amazing. Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
