How to use unique target to update imported nodes?

This should work:
- choose again one of your fields as a source;(1st column)
- choose GUID as a target;(2nd column)
- now you'll find a checkbox in the 3rd column. Set this, and the combination nid-guid is stored in a special table, to be referenced during the next import.

I have the same question.

The thing is, I have existing nodes. Those nodes have no GUID. So if I do an import, there is no way to determine whether they are duplicates.

I'm thinking that what I'll have to do is import just one record, then look for the "special table" and manually add a whole lot of rows to that table (one for every node) before attempting to bring in the feed.

Is there a better way?

I have no doubt that this works as designed.

smscotton, What you want is a wish of mine, too. I think there is a patch in the issuequeue which allows you to you a 'normal 'node field as GUID, but I cannot find it back. If you find it, or have an alternative solution, please post it.

I'm looking for the same feature in D7 version.
I want to manually create a node and update just some value with feeds using the title as unique ID.
Any advice?

I think that using custom fields as a unique target is covered by #661606: Support unique targets in mappers.

By "custom fields" I mean any field besides nid, url, or guid.

The same feature is needed...

for 7.x-2.x, try this:

1. Manually create nodes (before or after creating importer)
2. Create importer:
   • install unique field module (http://drupal.org/project/unique_field) and configure title as unique
   • Apply patch at http://drupal.org/node/661606#comment-4957878
   • In the node processor settings, select "Update existing nodes".
   • In the node processor mappings, set title to unique target
3. Import

If this works, comment on if the patch works for you and with what version you used it.

Thnx,

It worked fine for me. I have also found this patch today =)

My versions are:

Drupal | 7.7
Unique Field | 7.x-1.0-rc1
Feeds | 7.x-2.x-dev

I added this to the documentation also: http://drupal.org/node/1307732#field_as_unique_id_7

Is there any patch available for Drupal 6 also?

@gaurav The following works for me in 6.x to update nodes using a CSV parser (no additional modules or patches needed):

1. Include the nid of the nodes being updated as a column in your CSV,
2. In the node processor "mapping" settings, create a mapping from the nid column in the CSV(source) to "Node ID" (target)
3. Mark the "unique target" checkbox next to "Node ID" (do NOT mark the checkbox next to GUID if you have it)
4. In the node processor "options" settings, make sure the "Update existing nodes" radio button is selected

Using this set-up I am able to update nodes even if they were not created using the feeds module. Hope this helps someone!

Is this the same process necessary to update products by SKU in Drupal Commerce using Commerce Feeds?

Currently I get a uniqueness violation whenever I try to update the stock levels of a preexisting product...

The import doesn't seem to consider some settings of content type . I installed the unique field module and set two fields as unique .

This setting is not considered by the feeds module . It imports and creates duplicate entries for the unique fields also.

Please continue in #661606: Support unique targets in mappers.
