Instance Method Details

#contain_all(other) ⇒ Object

Check if the receiver contains all of the keys in the given array:

jsonb_op.contain_all(:a) # (jsonb ?& a)

# File 'lib/sequel/extensions/pg_json_ops.rb', line 270

def contain_all(other)
  bool_op(CONTAIN_ALL, wrap_input_array(other))
end

#contain_any(other) ⇒ Object

Check if the receiver contains any of the keys in the given array:

jsonb_op.contain_any(:a) # (jsonb ?| a)

# File 'lib/sequel/extensions/pg_json_ops.rb', line 277

def contain_any(other)
  bool_op(CONTAIN_ANY, wrap_input_array(other))
end

#contained_by(other) ⇒ Object

Check if the other jsonb contains all entries in the receiver:

jsonb_op.contained_by(:h) # (jsonb <@ h)

# File 'lib/sequel/extensions/pg_json_ops.rb', line 291

def contained_by(other)
  bool_op(CONTAINED_BY, wrap_input_jsonb(other))
end

#contains(other) ⇒ Object

Check if the receiver contains all entries in the other jsonb:

jsonb_op.contains(:h) # (jsonb @> h)

# File 'lib/sequel/extensions/pg_json_ops.rb', line 284

def contains(other)
  bool_op(CONTAINS, wrap_input_jsonb(other))
end

#has_key?(key) ⇒ Boolean Also known as: include?

Check if the receiver contains the given key:

jsonb_op.has_key?('a') # (jsonb ? 'a')

Returns:

• (Boolean)

# File 'lib/sequel/extensions/pg_json_ops.rb', line 298

def has_key?(key)
  bool_op(HAS_KEY, key)
end

#pg_jsonb ⇒ Object

Return the receiver, since it is already a JSONBOp.

# File 'lib/sequel/extensions/pg_json_ops.rb', line 304
