Get issues list filtered by custom field

[napless]

Hi, i need to get a list of all issue opened filtered by a custom field (id 17) that contain a date (ex. 2019-09-26).
How i can create this?
I've tried with this code, but the filter doesn't work.

`IssueManager issueManager = mgr.getIssueManager();
ResultsWrapper issues = null;

    Params params = new Params()
            .add("set_filter", "1")
            .add("f[]", "project_id")
            
            .add("v[project_id]", projectKey)
            .add("f[]", "cf_17")
            .add("op[cf_17]", "~")
            .add("v[cf_17]", "2019-09-26");
    try {
		issues = issueManager.getIssues(params);
		List<Issue> iss = issues.getResults();
		
		System.out.println(iss);
	} catch (RedmineException e1) {
		e1.printStackTrace();
	}

have you tried the corresponding request via curl, outside of the library? please check if this works first. if this works via curl but does not work in the library, feel free to provide a PR with a fix, please specify your Redmine version in this case since this may be version-specific

Hi Alexey.
with this curl, i get the issues that i want to retrieve.

http://redminefqdn/issues.xml?project_id=29&status_id=*&cf_17=2019-12-11

I think that the problem is in the "params" variable... could you help me to make right filter params variable?

Thank you in advance!

yeeeahh.. sorry for double post, but with this code, i've get the list of issues based on filter applied on custom field 17. :)

Only problem is that my custom field is a string, but contain a date, and i cannot apply the ">" "<" operator. Could you confirm that this isn't possible?

Params params = new Params()
.add("cf_17", "2019-12-11")
.add("project_id", "29")
.add("status_id", "*");

Thank you so much!

you can explore Redmine search params by constructing any query with ">=" and similar operands, e.g.
https://www.redmine.org/projects/redmine/issues?utf8=%E2%9C%93&set_filter=1&f%5B%5D=status_id&op%5Bstatus_id%5D=o&f%5B%5D=created_on&op%5Bcreated_on%5D=%3E%3D&v%5Bcreated_on%5D%5B%5D=2020-01-01&f%5B%5D=&c%5B%5D=tracker&c%5B%5D=status&c%5B%5D=subject&c%5B%5D=updated_on&c%5B%5D=category&group_by=

then apply the same parameters when calling Redmine using the library. the library simply forwards your params to the server, so whatever your server accepts in the URL should work in the library. with a possible exception when REST calls do not support some operations, which may happen.
