Function Details

delete/2

delete(Db, Document) -> any()

Deletes a list of documents if you want to make sure the doc it emptied on delete, use the option {empty_on_delete, true} or pass a doc with just _id and _rev members.

delete/3

delete(Db::db(), Document::map() | list(), Options::list()) -> {ok, _Result} | {error, _Error}

Deletes a list of documents if you want to make sure the doc it emptied on delete, use the option {empty_on_delete, true} or pass a doc with just _id and _rev members.

exists/2

exists(Db::db(), DocId::binary()) -> boolean()

test if doc with uuid exists in the given db

get/2

get(Db, DocId) -> any()

Equivalent to open_doc(Db, DocId, []).

open a document

get/3

get(Db::db(), DocId::binary(), Params::list()) -> {ok, map()} | {error, term()}

open a document Params is a list of query argument. Have a look in CouchDb API

lookup_rev/2

lookup_rev(Db, DocId) -> any()

get the last revision of the document

lookup_rev/3

lookup_rev(Db, DocId, Params) -> any()

save/2

save(Db, Doc) -> any()

Equivalent to save(Db, Doc, []).

save a document

save/3

save(Db::db(), Doc, Options::list()) -> {ok, Doc1} | {error, Error}

save a *document A document is a Json object like this one:

          {[
           {<<"_id">>, <<"myid">>},
           {<<"title">>, <<"test">>}
       ]}

Options are arguments passed to the request. This function return a new document with last revision and a docid. If _id isn't specified in document it will be created. Id is created by extracting an uuid from the couchdb node.

save/4

save(Db::db(), Doc::doc(), Atts::mp_attachments(), Options::list()) -> {ok, doc()} | {error, term()}

save a *document with all its attacjments A document is a Json object like this one:

          {[
           {<<"_id">>, <<"myid">>},
           {<<"title">>, <<"test">>}
       ]}

If the attachments is not empty, the doc will be sent as multipart. Attachments are passed as a list of the following tuples:

- {Name :: binary(), Bin :: binary()} - {Name :: binary(), Bin :: binary(), Encoding :: binary()} - { Name :: binary(), Bin :: binary(), Type :: binary(), Encoding :: binary()} - { Name :: binary(), {file, Path :: string()}} - { Name :: binary(), {file, Path :: string()}, Encoding :: binary()} - { Name :: binary(), Fun :: fun(), Length :: integer()} - { Name :: binary(), Fun :: fun(), Length :: integer(), Encoding :: binary()} - {Name :: binary(), Fun :: fun(), Length :: integer(), Type :: binary(), Encoding :: binary()} - { Name :: binary(), {Fun :: fun(), Acc :: any()}, Length :: integer()} - { Name :: binary(), {Fun :: fun(), Acc :: any()}, Length :: integer(), Encoding :: binary()} - { Name :: binary(), {Fun :: fun(), Acc :: any()}, Length :: integer(), Type :: binary(), Encoding :: binary()}.

where

Type` is the content-type of the attachments (detected in other
  case) and `Encoding` the encoding of the attachments:
  `<<"identity">>

if normal or <<"gzip">> if the attachments is gzipped.
