Drupal Aggregator

The default Aggregator Drupal module does not work very well. There are several problems with the Drupal Core module, one of which we have not fixed in our version (i.e. the flatness of the item table.)

There is a list of the known issues and our comments and whether we fixed the problem:

Problem Solution in m2osw's version of Aggregator
Missing XML marker The <?xml ... ?> marker is missing from some RSS feeds, add it as required
Spurious data Some RSS feeds add spurious data ...

Using the Taxonomy VTN View feature

One of the options to link terms in a vocabulary to their view is:


This option sends you to that path, exactly (where voc-xxx and term-xxx are numbers representing the vocabulary identifier and term identifier respectively.)

As is, it will tell you that the page does not exist. This is because the taxonomy_view path is to be created with the View module. To create a taxonomy VTN view, you want to define two arguments:

  • Vocabulary, and
  • Term.

The result is a list of nodes that you can control with very high granularity, sort the way you want them ...

Extend To Do List with other modules


The To Do List module can be extend with the use of other modules. This page describes such extensions and what you can do with them.


You may want to allow more people to work on your To Do List with better granularity in regard to who can edit which issue (instead of all of them) and who can view issues.

There are two modules you can use for this pupose. One lets you choose based on a set of taxonomy terms and the other lets you choose based on available roles.

In order to use a taxonomy with a set of terms, use tac_lite1

  • 1. tac_lite stands for Taxonomy ...

Insert Node Known Issues

The following are problems that have not been resolved and will probably not be.

Tag not transformed

At times, you enter the tag as in [node:123 cck=title] and it is not converted by the filter.

There are 3 common reasons for this to append:

  1. You did not select the filter in your Input formats;
  2. You did not select the format that uses the filter in that node; or
  3. There is a syntax error in the tag.

The 3rd one is certainly the most likely explanation once you made sure that the filter was effectively selected for that node. In many cases, it will be the missing ...

Parent/Child with Taxonomy VTN

Terms in a taxonomy can be organized as children of other terms. This generates a parent/child organization. For instance, you can have a term Fruit and mark Apple and Peach as children of Fruit.

The parent/child relationship can be used when you organize your Taxonomy VTN to shorten each page of your dictionary. The idea is simple: whenever you enter the top dictionary (taxonomy) page, you only get a list of the root terms (terms that are not children of other terms.) That list gives you access to the children terms and/or nodes of the parent term.

Creating Groups with Taxonomy VTN

Taxonomy VTN adds many fields in your taxonomy forms. When editing your taxonomy, one field is called Taxonomy VTN Group. This field is used to group different vocabularies (i.e. taxonomies) together in a group.

For instance, you could have three names such as: Kitchen, Utensils, Stainless Steel. Then another vocabulary could mention Kitchen and yet another Utensils, Wood.

The groups change the display in the Taxonomy VTN root page. A specific group can also be accessed using the URL:

One or two of the taxonomy columns are too wide

It happens that a column in your main display look too wide. Say you use three columns, one may be real large and two are the normal size (1/3rd of the screen.)

In general this happens because you have a URL in one of your description. (If the URL is in the title, I strongly advice that you move it to the description.) Then the description shows up as wide as that URL. Long URLs will have a real bad effect making the column much wider.

There are two ways to solve the problem:

  1. Create a tiny URL, although tiny URLs may still be too big, it may help
  2. Change the settings of the ...

Problems with Taxonomy VTN and their solution

The following are different problems you may encounter whenever you work with Taxonomy VTN. Those problems usually  have a work around and the following pages tell you about the solutions available to you.

Taxonomy VTN (The Module —)
