Is this possible?</a> </p> </blockquote> <p>I have 5 or 6 variable assignments of the form</p> <pre><code>var analyteSelection = new TemplatedSelectionContainer($('.analyte-container', this), helpers, optionsTemplate); var instrumentSelection = new AssetBackedSelection($('.instrument-container', this), helpers, optionsTemplate, Assets.instruments, 'Instrument'); var methodSelection = new AssetBackedSelection($('.method-container', this), helpers, optionsTemplate, Assets.methods, 'Method'); </code></pre> <p>As you can see, a significant amount of portion of these constructors are very much alike. It would be nice if I could create a little generic currying builder that would allow me to do something like:</p> <pre><code>var newSel = selectionContainerBuilder(this, helpers, optionsTemplate) var analyteSelection = newSel(TemplatedSelectionContainer, '.analyte-container'); var instrumentSelection = newSel(AssetBackedSelection, '.instrument-container', Assets.instruments, 'Instrument'); var methodSelection = newSel(AssetBackedSelection, '.method-container', Assets.methods, 'Method'); </code></pre> <p>I can achieve something similar with</p> <pre><code>var selectionContainerBuilder = function(ctx, helpers, optionsTemplate) { return function(FuncDef, selector, a, b, c, d, e, f) { return new FuncDef($(selector, ctx), helpers, optionsTemplate, a,b,c,d,e,f); } } </code></pre> <p>But seriously ick. I would like to just be able to splice the first three known parameters to the beginning of the arguments array and apply it to the FuncDef but I'm being foiled by the need to use the new operator.</p> <p>And before someone asks, I can't do new-operator enforcement inside of FuncDef because it's being generated by the coffeescript class keyword.</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.
