struct Proposal{
uint32 id;
string text;
bytes docs;
bool selected;
uint expectedBudget;
address submitter;
}
// _text and _expectedBudget already define.
Proposal proposal = Proposal({
id:getId(),
text:_text,
docs:<what_should_I_use_here>,
selected:false,
expectedBudget:_expectedBudget,
submitter: msg.sender
})
