i want write file in real time(instead of waiting code finish) flushing, doesn't seem change anything. here's code: datafile =open("json",'a+') def write(data): datafile.write(data) datafile.flush() also datafile.close() didn't change anything. know problem is? edit: managed make work adding os.fsync(datafile.fileno()) right after datafile.flush() you must use standard python library json https://docs.python.org/3.3/library/json.html i think use of open file inside function global name not correct.

i've come across reject_if in cocoon's readme , , in documentation nested attributes . rationale using reject_if when associated active record objects can determine whether they're valid or not? for nested objects, may not want attempt submit record :all_blank or other reason may want check on. point being, empty or incomplete (in way) object can, way, not built / added nested objects collection. validations serve different purpose. if empty object, say, fails validation whole form submit fail. reject_if approach allows submission succeed in such case removing object consideration before validations fire.

popular way ( 1 , 2 ) custom painting of items in datagridviewcombobox handling of event datagridview1. editingcontrolshowing , setting drawitem event handlers there: private void datagridview1_editingcontrolshowing( object sender, datagridvieweditingcontrolshowingeventargs e) { theboxcell = (combobox) e.control; theboxcell.drawitem += theboxcell_drawitem; theboxcell.drawmode = drawmode.ownerdrawvariable; } you see wrong: uses control-level event handle work columns. if have 50+ datagridviews? painting of custom combo boxes should handled per column instance , leaving control level intact. minimal implementation of per-column handling below. problem have ondrawitem() method not getting called. missing? (you can see fuchsia background override the same class working.)

a settings form example. on submit, appropriate collection needs updated; , 1, some, none or of fields need updated. assuming i'm not mistaken, mongoose: ignores fields aren't defined in schema. does low-level validation on field based on schema (i.e. reject, (ignore?) value isn't of correct type). so mean following advisable ? .put(function(req, res, next) { if (mongoose.types.objectid.isvalid(req.params._id)) { collection.update({_id: req.params._id}, { $set: req.body}, function (err, collection) { if (err) return next(err); res.send(200, {success: true}); }) }else{ res.send(400, {success: false}); } }) i.e. passing req.body directly update? it works, can't feel it's little lacking in validation/filtering? mongoose doing enough in schema approach sufficient? or should iterating on each expected field? i'm happy set tests thought i'd check community , sanity check approach - suggested alternatives gratef
