<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE =edge">
<meta name="viewport" content = "width=device-width,initial-scale=1">
<title>
{% block title %}WebNet{% endblock %}

<div class="form">
<div class="form-title">心脏毒性网络</div>
<div class="form-body">
<form class="navbar-form" action="/netapp/search" method="post" role="search"> {% csrf_token %}
<table>
<input type="text" class="form-control" name="chem_name" size="60" maxlength="60" placeholder="Chemical Name">

}
9. Design View
from django.shortcuts import render
from django.http import HttpResponse
from tasks import chem_gene_query
# Create your views here.
def index(request):
return render(request,"netapp/index.html") def search(request):
if request.method == "POST":
message = request.POST["chem_name"]
result = chem_gene_query(message)
return render(request,"netapp/result.html",{"result":result})
return render(request,"netapp/index.html")
10. add scripts in project
#!/usr/bin/env/python
# -*- coding:UTF-8 -*-
from __future__ import print_function
import MySQLdb
import sys def mysql_connect():
try:
conn = MySQLdb.connect(host="localhost",user="tcd_net",
passwd='tcd_net',db='ctd_net',port=3306,charset='utf8')
cur = conn.cursor()
return conn,cur
except MySQLdb.Error,e:
print(e.args)
sys.exit(1) def query_db(conn,cursor,command):
try:
cursor.execute(command)
conn.commit()
results = cursor.fetchall()
return results
except MySQLdb.Error,e:
print(e.args)
sys.exit(1) def chem_gene_query(chem):
conn,cur = mysql_connect()
query_command = """select chemicalName,chemicalID,casId,
genesymbol,geneid,geneforms,organism,organismid,interaction,
interactionActions,pubmedid from chem_gene where chemicalName = "%s";"""%chem
chem_gene_result = query_db(conn,cur,query_command)
result = []
keys = ["chemicalName","chemicalID","casId","genesymbol",
"geneid","geneforms","organism","organismid",
"interaction","interactionActions","pubmedid"]
for res in chem_gene_result:
out = {}
for i in range(len(res)):
out[keys[i]] = res[i]
if out:
result.append(out)
return result
11. Design results Display
{% extends "netapp/base_netapp.html" %}
{% block body %}
<link href="/static/netapp/css/search.css" rel="stylesheet">
<section class="content">
<div class="container-fluid">
<table class="table table-bordered table-condensed">
<caption>SearchResults</caption>
<thead>
<tr>
<th>chemicalName</th>
<th>genesymbol</th>
<th>interactionActions</th>
<th>pubmedid</th>
</tr>
</thead>
{% for i in result %}
<tbody>
<tr>
<td>{{ i.chemicalName }}</td>
<td>{{ i.genesymbol }}</td>
<td>{{ i.interactionActions }}</td>
<td>{{ i.pubmedid }}</td>
</tr>
</tbody>
{% endfor %}
</table>
</div>
</section>
