Hi,
If you have a 'set' or 'namedset' field, you could ty setting:
    input_style => 'short',

as an option for the field.

 

This will change the rendering from a radio-button to a multi-line select area.

You can also change how many options are shown by setting this:
    input_rows => 10,

 

If you set it to a value greater than the number of options you've defined, then it will just display all of them.

 

Cheers,

John

Hi,

It looks like you already have a field with this name in your EPrints configuration.  I would check across all of your cfg/cfg.d/ directory to see if you can find field configuration for this other 'course' field in another file or maybe earlier in eprint_fields.pl.

If this already exists and has values you would either need to add a new field with a different name or convert the existing field to a subject field.  A subject field has the same type of database field so the latter is possible.  However, it is likely that the values stored in this field will not be compatible with being a subject field.  So unless there are no values currently set for the existing course field, then I would not advise changing that field's config.

This has really gone beyond the point where it is easy to advise what to do, as there is a risk that I could give you the wrong advice because I don't know the exactly what fields you have and how they are being used.  I think the safest thing to do is to call the new subject field for course, course_id rather than just course, this should avoid the duplicate column issue.  This would change the IDs for the phrases you need to add and the config you need to add to your workflow. 

Once you have added this field and the subject tree it uses, you may want to map the values across for the original course field across to this new course_id.  If there are not many values, then it is easiest to do this manually.  If there is a lot of values you may want to write a script that can do the mapping.

Hi David,

 

There is an error like below :

 

Possible attempt to put comments in qw() list at (eval 162) line 36.

Starting EPrints Repository.
Connecting to DB ... done.
DBD::mysql::db do failed: Duplicate column name 'course' at /usr/share/eprints3/bin/../perl_lib/EPrints/Database.pm line 3052.
SQL ERROR (do): ALTER TABLE `eprint` ADD `course` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin
SQL ERROR (do): Duplicate column name 'course' (#1060)
Failed adding course to dataset eprint

if an error like that appears, do I have to create a new field? if for example I want to create a new field and the 'course' field is deleted, what should I do?

Hi Agung PW,

You need to make sure you add this configuration before the end of the eprint_fields.pl file.  In particular before the last line which should just be:

];

If not it will not pick this up as a new field.  Also, I would expect there to be a syntax error, if you put this right at the end of the file.  If you have a lot of eprint records, this will take a long time to run.  However, I would expect some output at the end even if no fields are added.  This is what I saw when I ran epadmin of a test repository I knew needed no new fields needed adding:
 
0 datasets added
0 fields added
0 counters were added

If it had added a new field (assuming it is called 'course') I would have expected to see something like:

Added course to dataset eprint
0 datasets added
1 fields added
0 counters were added

Hi David,

 

I have tried to enter the field into eprints_field.pl, but when I run the epadmin update ArchiveID command, the process takes a very long time and no notification has appeared.

Hi,

Subjects and Divisions boxes are subject type fields that include a part of the subject tree.  Therefore you would need to add a new sub-tree to your subject tree to include all your course options.  (You can use the Edit Subject page [1] linked from the Admin page to do this). Then you would need to add some configuration like the following to your archive's cfg/cfg.d/eprint_fields.pl file:

{
    name => 'course',
    type => 'subject',
    top => 'courses',
    browse_link => 'courses',
},

I have made some assumptions here:

1. That your would only ever need to store one course value against and eprint record.  If you need more you may need to add the line:

multiple => 1,

to the above configuration.

2. That the subject ID for the top of your courses sub-tree is 'courses'.

3. That you intend to create a browse view for courses like by default you will have for subjects and divisions.

Once you have added this configuration you will need to run the following command (substituting EPRINTS_PATH and ARCHIVE_ID) as appropriate:

EPRINTS_PATH/bin/epadmin update ARCHIVE_ID

Next you will need to add this field to your workflow. This will need a line like the following at the point you want this to appear in your workflow:

<component><field ref="course" /></component>

You may at this point also want to add some phrases.  You can does this via the Phrase Editor page link from the Admin page or edit a phrases file from the command line.  The minimum phrases you will need are eprint_fieldname_course and eprint_fieldhelp_course.

Once you have done all the is you will need to test the configuration is valid an reload the web server:

EPRINTS_PATH/bin/epadmin test
apachectl graceful

I have been working on improving the documentation pages about different types of metadata field as listed at https://wiki.eprints.org/w/Category:EPrints_Metadata_Fields.  I have not got to updating the subject field [2] yet but hope to do so today or later this week.  However, I hope to add some useful configuration examples to help when it comes to questions like yours here.

Hi,

 

I just added a field for a course with a lot of data. How can I make the view in the Details section so that it displays the course data like the divisions view or like Subject ?

 

 

Thank you.
