upload file through REST API is not displaying in UI

Arun_nmc

Hi ,

Using the (alfersco activiti exposed API) /activiti-app/api/enterprise/process-instances/52619/raw-content?isRelatedContent=false, i am trying to upload a file to a process instance id 52619. But only one file(sample.txt) alone is getting uploaded in the related_content table of the activiti.

I am using the alfersco activiti UI which is having the file upload component to display the associate file for the process.

when i am doing upload via UI for a task, i am able to see the document even in the completed task.

However whetn i am trying to upload the file through the API, its content is stored in the content table but i am not able to see in the UI. There is a column in the related_content table called 'field' this need to be updated with "fileupload"value. once it updated in the table, then i can able to see the file attachment in the UI.

Is there a way that i can update the field of related_content table as fileupload while uploading the file using the /activiti-app/api/enterprise/process-instances/52619/raw-content?isRelatedContent=false API

Kindly suggest your thoughts please.

Thanks

Hi,

There is a GET API activiti-app/api/enterprise/process-instances/{process-instance)/field-content through we can get the related-content table field column.

is there any API through which we can updated the field conlumn of the related_content table.

if the API is not there, whether setting the default value for the field column to 'fileupload' or create a trigger[ when ever upload is happen and insert valur into related-content] to update the field value after the file upload happens.

whether these to resolve this issue. Kindly suggest your thoughts please.

Hi,

i am able to find the solution on this.

whever a file get uploaded via REST API for a process instance id, the field column of the related_content table can be updated with the value fileupload by using data base triggers. could you please suggest adding data base triggers in the activiti Database is the right approach or not.

Kindly suggest your thoughts on this please.

Hi Arun,

I believe you are currently using the wrong API endpoint. Looking at the official documentation at

https://docs.alfresco.com/process-services1.10/topics/content.html

even the documentation states for the endpoint you are trying to use, that it "...currently won’t have any influence on what is visible in the UI".

In order to see content on a task, you should use the other API endpoint for tasks:

POST api/enterprise/tasks/{taskId}/raw-content

This one is also explained at the documentation page mentioned earlier.

Does attaching documents work with this endpoint so that you also see the content in the UI?

Please do not modify the database manually in any way, this is NOT required at all!

Best regards,

Dennis

Hi,

Thanks for your reply.

Yes, we tried for the task UI POST api/enterprise/tasks/{taskId}/raw-content , it get added the file visible in the related content field of the activiti UI

But we would like to see the file in the File upload filed of the UI screen.

So that’s why used api/enterprise/process-instances/{processInstanceId}/raw-content

API and created the database triggers specifically for adding the value fieldupload in the related_content’s field column in order to get display the file in the File Upload[customized] filed of Activiti UI.

This trigger wont cause any issues, but trying to understand whether its good practice to add database triggers in the activiti DB.
