Question

我定义了以下路线：

Route::get('/tours/{country_identifier}', ['as' => 'country', 'uses' => 'CountryController@index']);

现在我想使用

之类的东西链接到这个命名路线

route('country')

填写{country_identifier}参数的

，例如'/旅游/加拿大'。

我怎样才能实现这一目标？

Answer 1

您可以将参数作为第二个参数传递：

import numpy as np


old_array =  [ (3.0535400914168154, 0.371345899229, 0.312953794281, -0.0125231427371, 0.0),
(3.056684825749555, 0.373971853521, 0.313682391117, -0.0264543909236, 0.0),
(3.0598295600822953, 0.376861295611, 0.314535588286, -0.041169303628, 0.0)]

maxline = 20


# If you want fullfil extra dimension with NaN 
arr = [(np.NAN,)*len(old_array[0])]*(maxline - len(old_array))

# If you want fullfil extra dimension with anything else
# arr = np.array([(ANYTHING_YOU_WANT,)*len(old_array[0])]*(maxline - old_array.size))

new_ = old_array + arr

print numpy.array(new_)

>>

你可以看看documentation，那里有很多有用的例子：）

Answer 2

从视图使用链接（假设您使用刀片）

<a href="{{ URL::route('country', array('country_identifier' => $var)) }}">$var</a>

Answer 3

试试这个

route('country', array('country_identifier' => 'Canada'))

将加拿大＆＃39;作为参数进行路由。

Answer 4

简单：

单个链接

<a href="{{ route('country', ['country_identifier' => $country_id])  }}">$country_name</a>

如果您要生成一些链接，例如

@foreach($countries as $country)
<a href="{{ route('country', ['country_identifier' => $country->id])  }}">$country->name</a>
@endforeach

注意：$countries是传递给视图示例$countries = Country::all()

的模型对象

Laravel :(如何）可以使用参数链接到命名路由？
