startkey, endkey parameters aren't working

[denisok]

query: Options = [{startkey, [Date, list_to_bitstring(Branch)]}, {endkey, [Date, list_to_bitstring(Branch), {[]}]}], DesignName = "vetting", ViewName = "tests_groups", {ok, _ViewResults} = couchbeam_view:fetch(Db, {DesignName, ViewName}, Options).

Isn't working correctly.

That is because couchbeam_view.erl parsing startkey/endkeys atoms as: parse_view_options([{start_key, Value}|Rest], #view_query_args{options=Opts}=Args) -> Opts1 = [{"start_key", Value}|Opts], parse_view_options(Rest, Args#view_query_args{options=Opts1}); parse_view_options([{end_key, Value}|Rest], #view_query_args{options=Opts}=Args) -> Opts1 = [{"end_key", Value}|Opts],

but according to http://wiki.apache.org/couchdb/HTTP_view_API, this parameters should be named as "startkey" and "endkey".

CouchDB 1.1.1 was used to reproduce

[benoitc]

Both should be handled : https://github.com/apache/couchdb/blob/1.1.x/src/couchdb/couch_httpd_view.erl#L305

What is the error on couchdb side ?

[denisok]

no error at least in /usr/local/var/log/couchdb/couch.log. view just return all documents, seems just ignoring query.

I am using MacBook Pro, and installed couch with help of brew

[benoitc]

Can you define what isn't working and such. So far tests pass here.

[yfyf]

This is probably related to this: https://issues.apache.org/jira/browse/COUCHDB-949 You are probably using an old version of CouchDB, since CouchBeam uses the new "start_key" syntax.

[benoitc]

1.1.1 is supposed to have the support for these commands. I'm not sure what could be the problem here, Also I don't reproduce it.

[denisok]

I would like to help. Will try to find sources that brew is using to install couchdb. What else I could do to find what is the issue? Doc on wiki are confusing, that declares only startkey.

[denisok]

So I think issue is: I was confused by http://wiki.apache.org/couchdb/HTTP_view_API and used atom startkey instead of start_key for couchbeam. So couchbeam couldn't parse that atom.

But using atom start_key give me next exception: \ exception error: bad argument in function mochiweb_util:quote_plus/2 in call from mochiweb_util:'-urlencode/1-fun-0-'/2 in call from lists:foldr/3 in call from mochiweb_util:urlencode/1 in call from couchbeam:make_url/3 in call from couchbeam_view:make_view/4 in call from couchbeam_view:fetch/3 in call from if_couchdb:get_tests_groups/2

will try to figure out what is that.

[denisok]

tried to run mociweb_util:urlencode in erl shell with parameter: [{"start_key",[1324932287,<<"8a6a105b63b5e2d0">>]}]

give same exception. And this seems related to parameters that I pass to start_key.

[denisok]

same issue when I am not using atom, but passing "start_key": Options = [{"startkey", [Date, list_to_bitstring(Branch)]}, {"endkey", [Date, list_to_bitstring(Branch), {[]}]} ] Strange, because when I am passing "startkey" - everything works fine.

make_url:[{"end_key",[1324932287,<<"8a6a105b63b5e2d0">>,{[]}]}, {"start_key",[1324932287,<<"8a6a105b63b5e2d0">>]}] new:[{"start_key",[1324932287,<<"8a6a105b63b5e2d0">>]}, {"end_key",[1324932287,<<"8a6a105b63b5e2d0">>,{[]}]}] \ exception error: bad argument in function mochiweb_util:quote_plus/2 in call from mochiweb_util:'-urlencode/1-fun-0-'/2 in call from lists:foldr/3 in call from mochiweb_util:urlencode/1 in call from couchbeam:make_url/3 in call from couchbeam_view:make_view/4 in call from couchbeam_view:fetch/3 in call from if_couchdb:get_tests_groups/2

But using atom start_key - everything OK now ) Thanks.

[benoitc]

passing atoms is the way to do anyway. Thanks for the feedback :)
