file name as a key to upload

forumwebuser — Wed, 24 Nov 2010 13:05:58 GMT

Hello,Can someone explain me what is the impact of the names of the files in an alfresco repository?I created a simple workspace with a simple model. In my model I have some indexes/fields. In nowhere in this model I make a reference to the file name of the files I will upload as a field/index/key o

Your name property (cm:name) is probably being extracted from the file that you upload.

If you are uploading to a file folder structure that uses the cm:contains association (i.e. a bog standard alfresco file/folder structure) then there is a constraint to prevent duplicate names.

You could upload with a different primary association which does not have the unique name constraint but then your node will not show up in the interfaces that work off the file / folder service.

Perhaps the easiest approach would be to upload to different folders.

Alfresco stores files using XPath and cm:name, if you need to write a second version of the same file you have to enable versioning for that space.

In the contentModel.xml file you can find cm:contains association and I think that you can override the duplicate setting… I'm not sure about it and I don't know if Alfresco supports this type of changes.

Hope this helps.

First of all, thank you for your answers.

mrogers,

Im uploading to a file structure that uses my own model, but as far as I understand, I may get all the defaults from the contentmodel.xml, and that may be the reason why there is a restriction on the file name.

"You could upload with a different primary association which does not have the unique name constraint but then your node will not show up in the interfaces that work off the file / folder service."
Does this means that if I go to the alfresco web client site I will not be aqble to browse with success may file and folders?

"Perhaps the easiest approach would be to upload to different folders."
I cant do this, because the files are organized in folders related to business rules.

OpenPj,

"Alfresco stores files using XPath and cm:name, if you need to write a second version of the same file you have to enable versioning for that space."
Yes, Im already versioning files in some cases. The problem here is that accordingly to may indexes, the file actually doesnt exists! But because I will upload a file with the same name (but with different custom indexes) Alfresco will throw an error saying the file already exists.

"In the contentModel.xml file you can find cm:contains association and I think that you can override the duplicate setting… I'm not sure about it and I don't know if Alfresco supports this type of changes."

I saw it there, tanks. Can I overwrite it in my custom model? Any example? But if I overwrite it, will I still be able to browse the files in the alfresco web client web site?

In general Im searching for a way to ignore the file names of files when uploading. I want to control de existence of files only with my custom indexes/fields. At the same time I dont want to loose the possibility of brwosing the files using alfreaco web clients?

Any additional help is appreciated

thank you
