If you want only time, TimeField is what you need:
class ConversationHistory(models.Model): contact_date = models.DateField(_(u"Conversation Date"), blank=True) contact_time = models.TimeField(_(u"Conversation Time"), blank=True)
You can take advantage of the
class TimeField([auto_now=False, auto_now_add=False, **options])
A time, represented in Python by a datetime.time instance. Accepts the same auto-population options as DateField.
If you use the
auto_now_add, it will automatically set the field to now when the object is first created.
class ConversationHistory(models.Model): contact_date = models.DateField(_(u"Conversation Date"), auto_now_add=True, blank=True) contact_time = models.TimeField(_(u"Conversation Time"), auto_now_add=True, blank=True)
field_name = models.TimeField(auto_now=False, auto_now_add=False, **options) TimeField has the following extra optional arguments ‚Äì TimeField.auto_nowAutomatically set the field to now every time the object is saved. Useful for "last-modified‚" timestamps. Note that the current time is always used; it‚Äôs not just a default value that you can override. The field is only automatically updated when calling Model.save(). The field isn‚Äôt updated when making updates to other fields in other ways such as QuerySet.update(), though you can specify a custom value for the field in an update like that.
TimeField.auto_now_addAutomatically set the field to now when the object is first created. Useful for creation of timestamps. Note that the current time is always used; it‚Äôs not just a default value that you can override. So even if you set a value for this field when creating the object, it will be ignored. If you want to be able to modify this field, set the following instead of auto_now_add=True:
- For TimeField: default=datetime.time.now ‚Äì from datetime.now()
- For TimeField: default=timezone.now ‚Äì from django.utils.timezone.now()
Field parameters are arguments given to each field to apply some kind of constraint or pass a specific characteristic to a specific field. For example, adding the
null = True argument to the TimeField will allow it to store empty values ‚Äã‚Äãfor that table in a relational database.
Here are the field parameters and attributes that TimeField can use.
|Null||If True , Django will store empty values ‚Äã‚Äãas NULL in the database. Default is False.|
|Blank||If True , the field is allowed to be blank ... Default is False.|
|Choices||An iterable (eg, a list or tuple) of 2-tuples to use as choices for this field.|
|Default||The default value for the field. This can be a value or a callable object. If callable it will be called every time a new object is created.|
|help_text||Extra "help‚" text to be displayed with the form widget. It’s useful for documentation even if your field isn’t used on a form.|
|primary_key||If True, this field is the primary key for the model .|
|Unique||If True, this field must be unique throughout the table.|

TimeField — Django Models __del__: Questions
How can I make a time delay in Python?
I would like to know how to put a time delay in a Python script.
import time time.sleep(5) # Delays for 5 seconds. You can also use a float value.
Here is another example where something is run approximately once a minute:
import time while True: print("This prints once a minute.") time.sleep(60) # Delay for 1 minute (60 seconds).
You can use the
sleep() function in the
time module. It can take a float argument for sub-second resolution.
from time import sleep sleep(0.1) # Time in seconds

How to delete a file or folder in Python?
How do I delete a file or folder in Python?

How do I copy a string to the clipboard?
I"m trying to make a basic Windows application that builds a string out of user input and then adds it to the clipboard. How do I copy a string to the clipboard using Python?
ctypes seem to be an overkill for this simple task.
Tkinter is a cross-platform GUI framework, which ships with Python by default and has clipboard accessing methods along with other cool stuff.
If all you need is to put some text to system clipboard, this will do it:
from Tkinter import Tk r = Tk() r.withdraw() r.clipboard_clear() r.clipboard_append("i can has clipboardz?") r.update() # now it stays on the clipboard after the window is closed r.destroy()
And that"s all, no need to mess around with platform-specific third-party libraries.
If you are using Python 3, replace
Python script to copy text to clipboard
I just need a python script that copies text to the clipboard.
After the script gets executed i need the output of the text to be pasted to another source. Is it possible to write a python script that does this job?

Maybe there are another answers? What TimeField — Django Models exactly means?. I just hope that will not emerge anymore
