django中ModelForm save方法 以及快速生成空表单或包含数据的表单 包含错误信息

django中ModelForm学习系列一~save方法

Model代码

from django.db import models
# Create your models here. class ProjectInformation(models.Model):
"""
项目基本信息
""" ResearchClassify = (
('药物类','药物类'),
('器械类','器械类'),
('试剂类', '试剂类'),
('临床研究学', '临床研究学'),
('纵向课题', '纵向课题'),
('废止合同', '废止合同'),
('结题项目', '结题项目'),
) protype = models.CharField(max_length=30,verbose_name='项目类型')
proname = models.CharField(max_length=50,verbose_name='项目名称(中文)')
proenname = models.CharField(max_length=50,verbose_name='项目名称(英文)')
studytype = models.CharField(max_length=30, verbose_name='研究分类', choices=ResearchClassify)
clinicalnum = models.CharField(max_length=30, verbose_name='临床试验备案号')
leaderunit = models.CharField(max_length=5, choices=(('是', '是'), ('否', '否')),verbose_name='本院是否为组长单位') class Meta:
verbose_name = '项目名称(中文)'
verbose_name_plural = verbose_name def __str__(self):
return self.proname

Form代码

from django import forms
from django.forms import ModelForm
from .models import ProjectInformation class ProjectInformationForm(ModelForm):
class Meta:
model = ProjectInformation
localized_fields = ('__all__') exclude = ['add_time','filetype',] widgets = {}
error_messages = {
'protype': {
'required':'这是个必填项目', #生成错误信息
},
}

View代码

def MyProjectSave(request):
"""
保存表单信息
""" form = ProjectInformationForm(request.POST) if request.method == 'POST': if form.is_valid(): all_data = form.clean()
form.save()
else:
error = form.errors #错误信息
return render(request, 'forms.html', {'form': form, 'error': error}) return render(request, 'forms.html', {'form': form})
# return HttpResponseRedirect('/myprojectsave/')

HTML 代码

<form id = '' name='' action="{% url 'myprojectsave' %}" method="post" autocomplete="off">
<div class="modal-body">
{% for field in form %}
{{ field.errors }}
<div id = form_row class="row"> <div class="form-group">
<div class="col-lg-2 form_span chart-container">
<span>{{ field.label_tag }}</span>
</div>
<div class="col-lg-10 form_span chart-container">
{{ field }}
</div>
</div>
</div>
{% endfor %}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">关闭
</button>
<button type="submit" id = "jsLoginBtn" class="btn btn-primary">
提交更改
</button>
</div>
{% csrf_token %}
</form>

根据model form生成空表单或包含数据的表单

Model代码

class CeShi(models.Model):
realname = models.CharField(max_length=10,verbose_name='姓名',default='')
nickname = models.EmailField(max_length=10, verbose_name='昵称', default='')

Form代码

class IndexForm(ModelForm):
class Meta:
model = Ceshi
localized_fields = ('__all__') # exclude = ['active', 'is_staff', 'first_name', 'is_active', 'date_joined', 'password', 'username', 'email',
# 'is_staff', 'last_login', 'password', 'last_name', 'date_joined', 'is_superuser'] fields = ['realname','company','company_type','project_role','company_person',
'registration_number','department','title','education','gender','gcp',
'contact_person','mobile','address','introduction'] widgets = {} #可以自定义widgets属性包括id,class
       #widgets = {
# 'username': forms.TextInput(
# attrs={
# 'class': 'form-control',
# 'placeholder': '用户名',
# 'id': 'user_name',
# 'required': '请填入用户名',
# }), # 'password': forms.TextInput(
# attrs={
# 'class': 'form-control',
# 'placeholder':'密码',
# 'id':'pass_word',
# 'required':'请填入密码',
# 'type':'password',
# })
#}

View代码

    form = IndexForm(auto_id = False)  #生成空表单

    # user = get_object_or_404(CeShi, username=username)
# form = IndexForm(instance=user)
#CeShi代表数据库,username代表字段建议用id,IndexForm代表form字段
print(form) return render(request, 'index.html', {'form':form})

HTML代码

<form action="{% url 'usermessage' username %}" method="post" autocomplete="off">
{% for field in form %} {{ field.errors }}
<div class="row">
<div class="form-group">
<div class="col-lg-2 form_span chart-container">
<span>{{ field.label_tag }}</span></div>
<div class="col-lg-10 form_span chart-container">{{ field }}</div></div>
</div>
{% endfor %}
<input class="btn btn-green" id="jsLoginBtn" type="submit" value="提交 > " /> {% csrf_token %} </form>
