小编use*_*271的帖子

我正在尝试使用 DateInput，但Required argument 'year' (pos 1) not found在此处出现以下错误 {{ form.incident_date_time_reported|add_class:"form-control"}}（第 52 行）

表格.py

from django import forms
import datetime
from functools import partial
DateInput = partial(forms.DateInput, {'class': 'datepicker'})

class IncidentForm(forms.Form):

    incident_date_time_reported = forms.DateField(initial=datetime.date, required=False, widget=forms.DateInput)

    def search(self):

        # cleaning the data
        incident_date_time_reported = self.cleaned_data.get('incident_date_time_reported')

        query = Incident.objects.all()

        if incident_date_time_reported is not None:
            query = query.filter(incident_date_time_reported=incident_date_time_reported)


        return(query)

class CapaForm(forms.Form):
    capa = forms.CharField(required=False)

提交表单后,我想检查capa字段的格式.我想要求用户正确输入capa格式为6个数字,短划线和两个数字.(###### - ##)

def search(self):
    capa = self.cleaned_data.get('capa', None)

    if ("\d{6}\-\d{2}" or None) not in capa:
            raise forms.ValidationError("CAPA format needs to be ######-##!")

它目前不允许我提交格式正确的capa并抛出ValidationError.我认为问题是我正在尝试将正则表达式与对象进行比较.如何检查用户尝试提交的'capa'的格式？

*********UPDATE

当我在CAPA字段中输入错误的格式时,现在一切正常.我收到错误The view incidents.views.index didn't return an HttpResponse object. It returned None instead.这与我所做的更改有关吗？

from django.core.validators import RegexValidator
my_validator = RegexValidator("\d{6}\-\d{2}", "CAPA format needs to be ######-##.")

class CapaForm(forms.Form):
    capa = forms.CharField(
        label="CAPA",
        required=False, # Note: validators are not run against empty fields
        validators=[my_validator]
        )

我无法弄清楚shell /usr/bin/virtualenvwrapper.sh在服务器登录时尝试运行的位置.我希望virtualenvwrapper永久卸载,而不仅仅是从shell实例中删除.我以为我卸载了它pip uninstall virtualenvwrapper,但每次登录服务器时我都会收到错误-bash: /usr/bin/virtualenvwrapper.sh: No such file or directory,好像有一些剩余的工件.昨天我做了很多修修补补,我记不起所做的所有改变或者我是如何做到这一点的.它在哪里执行搜索virtualenvwrapper.sh？

我正在创建自定义身份验证登录.除了在电子邮件和密码不正确时显示错误消息外,一切似乎都有效.

我知道这与登录失败时我对login.html页面的呈现有关,而且没有提供表单,因为尝试登录失败这一事实,但我不知道如何将其放入我的代码.

logout(request) #logs out user upon reaching the /login/ page

if request.POST:
    email = request.POST['email']
    password = request.POST['password']

    user = authenticate(email=email, password=password)
    if user is not None:
        if user.is_active:
            login(request, user)

我正在尝试在forms.py中动态创建查询.我将它存储为字符串,然后尝试过滤并返回它,但我收到错误...

filter() argument after ** must be a mapping, not str

到底是怎么回事？显然它不喜欢它.它应该是不同的数据类型吗？

forms.py

from django import forms
from django.db.models import Q

from .models import Incident
from .models import Equipment


class IncidentForm(forms.Form):
    incident_id = forms.IntegerField(required=False)
    equipment_id = forms.ModelChoiceField(Equipment.objects.all(), required=False, widget=forms.TextInput)

    def search(self):

        # cleaning the data
        cust_id = self.cleaned_data.get('incident_id')
        equip_id = self.cleaned_data.get('equipment_id')

        user_input = [cust_id, equip_id]

        # finding blank fields
        i = 0
        lst=[]
        for x in user_input:
            if x != None:
                lst.append(i)

用[3]数值对Hash of Arrays进行排序的最简单方法是什么？

例如......我想从最大值到最小值对值为6125,1686,700的散列进行排序.我最初虽然把这些值作为键,但其中一些数字在其他数组中是相同的.

'12' => [
     '+',
     'ATGGTTTTCTTCTCTCCTTCCCTCTCCAGCCTGCTGTATAAGTAA',
     'MGLGLAPSWPSLLTSSYPECVPYLFSHLLPPTTQPYPFSPSLSSLLYK*',
     6125
     ],
'41' => [
     '+',
     'ATGGGAGTTTACTGTGATGACTTGAGGACAGAGGGACTCTAG',
     'MGVYCDDLRTEGL*',
     1686
     ],
'16' => [
     '+',
     'ATGGGAGTTTACTGTGATGACTTGAGGACAGAGGGACTCTAG',
     'MGVYCDDLRTEGL*',
     700
     ]
