python - Multiple default values specified for column "id" of the table -

-

i use run website on laptop , database sqlite, wanted transfer digitalocean , changed database postgresql, when migrate encounters problems.

python 3.4 django 1.8

error

django.db.utils.programmingerror: multiple default values specified column "id" of table "profiles_userprofile"

my model

class userprofile(models.model):     user = models.onetoonefield(user)     avatar = models.imagefield(blank=true, upload_to=get_image_path, default='/static/image/avatar/male.png')     age = models.integerfield(default=4, validators=[minvaluevalidator(3), maxvaluevalidator(99)])

what should do?

try explicitly specifying id field , marking primary key:

class userprofile(models.model):     id = models.bigintegerfield(primary_key = true)     user = models.onetoonefield(user)     avatar = models.imagefield(blank=true, upload_to=get_image_path, default='/static/image/avatar/male.png')     age = models.integerfield(default=4, validators=[minvaluevalidator(3), maxvaluevalidator(99)])

django should automatically create sequence field.

it may user foreign key without explicitly defined primary key confusing orm, although that's theory.

      Delete everything from the migrations folder (except __init__.py), also delete the .SQLite database file as well. If using PostgreSQL delete database and set it up afresh. Then rerun
      the python manage.py commands;

      python manage.py makemigrations
      python manage.py migrate
      python manage.py runserver

      Delete

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
