  1. POReference error: "Tags is not defined"
    text
    copied!<p>I have manipulated the code in <a href="https://github.com/dtryon/clog" rel="nofollow">this application</a>, and put in a sidebar in the views/layout.jade file. In the sidebar I've cut/pasted the code for handling tags from views/index.jade:</p> <pre><code> ul.tags each tag in tags a(href='/tag/' + tag._id.toHexString()) li.tag= tag.name </code></pre> <p>The tags are fetched from the db as they should, and rendered out in the sidebar, however when I click on one of them (which should show a new page with all the posts tagged with the tag) I get an error message:</p> <pre><code>500 ReferenceError: ... layout.jade:10 8| p 9| ul.tags &gt; 10| each tag in tags 11| a(href='/tag/' + tag._id.toHexString()) 12| li.tag= tag.name tags is not defined </code></pre> <p>Here's the function that's called in the file "tagcontroller.js" (that's handling the logic for the tags):</p> <pre><code>app.get('/tag/:id', function(req, res){ model.Tag.findById(req.params.id, function (err, tag){ if (err) { console.log(err); // do something } var query = blogModel.BlogPost.find( { _id: { $in : tag.blogs } } ); query.where('date').lte(new Date()); query.exec(function (err, blogs) { if (err) { console.log(err); // do something } var query = model.Tag.find({}); query.exec(function (err, tags) { if (err) { console.log(err); // do something } res.render('tags/detail', { title: tag.name, blogs: blogs, tagList: tags, dateFormatter: dateFormatter }); }); }); }); }); </code></pre> <p>If I put back the code into views/index.jade, everything works fine. But I need to have it in layout.jade to be able to show it on every page, not only on Home (index.jade).</p> <p>I would really appreciate some help!</p>
