python - Django 的序列数据库？

Question

我正在学习 Django 并创建一个生物序列数据库，包含使用如下所示模型的数百个序列，模型有两个字段，“Seq_ID”和“sequence”。我正在尝试编写一个 View ，以便它可以在主页上呈现所有序列的 ID，然后单击特定的 ID，它将显示关联的序列。

更新的 View 和网址:

型号:

from __future__ import unicode_literals

from django.db import models

    # Create your models here.
class FastaSeq(models.Model):

    Seq_ID =  models.CharField(max_length=20)
    Sequense = models.TextField()

    def __unicode__(self):

        return self.Seq_ID

查看:

from django.shortcuts import render
from django.conf import settings 
from .models import FastaSeq

def home(request):
    data = FastaSeq.objects.all()
    context = {'data':data}
    template = 'home.html'
    return render(request, template, context)

def single(request,Seq_ID):
    data = FastaSeq.objects.get(Seq_ID=Seq_ID)
    return render(request,template,{'data':data})

网址:

from django.conf.urls import url
from django.contrib import admin
from new_app import views as new_app_view



urlpatterns = [

    url(r'^admin/', admin.site.urls),
    url(r'^home/', new_app_view.home, name='home'),
    url(r'^User/(?P<Seq_ID>\d+)/$', new_app_view.single, name='single'), 

]

示例数据:

Seq_ID:
>01_sequence

Sequence:

HGVDLSHVYGESLERQHNRRLFKDGKMKYQMINGEMYPPTVKDTQVEMIYPPHIPEHLKFAVGQEVFGLV

使用此模型，我已将大约 50 个演示序列添加到数据库中，但无法写下可以在主页上显示序列 ID 的 View ，并且单击 ID 将使您看到序列数据。

更新:

显示一些错误:

No    return force_text(iri_to_uri(resolver._reverse_with_prefix(view, prefix, *args, **kwargs)))
  File "/home/jai/.virtualenvs/env1/local/lib/python2.7/site-packages/django/urls/resolvers.py", line 389, in _reverse_with_prefix

Answer 1

from .models import FastaSeq
def home(request):
    data = FastaSeq.objects.all()
    context = {'data':data}
    template = 'home.html'
    return render(request, template, context)

在模板中

{% for d in data %}
<a href="{% url 'single' d.Seq_ID %}">{{ d.Seq_ID  }}</a>
{% endfor %}

在 urls.py 中

url(r'^User/(?P<Seq_ID>[\w{}.-]{1,40})/$', 'views.single', name='single'), 

创建另一个 View

def single(request,Seq_ID):
    data = FastaSeq.objects.get(Seq_ID=Seq_ID)
    return render(request,template,{'data':data})

在单个函数模板中`

{{ data.Seq_ID }}
{{ data.Sequense }}
