46 This module helps you to map various DBIx::Class features to CGI
47 parameters. For the most part that means it will help you search,
48 sort, and paginate with a minimum of effort and thought.
49
51 dbic_config
52 $self->dbic_config({
53 schema => MyApp::Schema->connect(@connection_data),
54 connect_info => { ... },
55 });
56 You must run this method in setup or cgiapp_init to setup your schema.
58 Valid arguments are:
60 schema - Required, Name of DBIC Schema
62 connect_info - Optional, these arguments are what are passed to connect, if
63 this isn't passed and a C<dbh> method exists, that will be used
64 ignored_params - Optional, Params to ignore when doing a simple search or sort,
65 defaults to
66 [qw{limit start sort dir _dc rm xaction}]
67 page_size - Optional, amount of results per page, defaults to 25
69 page_and_sort
71 my $resultset = $self->schema->resultset('Foo');
72 my $result = $self->page_and_sort($resultset);
73 This is a helper method that will first sort (with "simple_sort") your
75 data and then paginate it. Returns a resultset.
76 paginate
78 my $resultset = $self->schema->resultset('Foo');
79 my $result = $self->paginate($resultset);
80 Paginates the passed in resultset based on the following CGI
82 parameters:
83 start - first row to display
85 limit - amount of rows per page
86 Returns a resultset.
88 schema
90 my $schema = $self->schema;
91 This is just a basic accessor method for your schema
93 search
95 my $resultset = $self->schema->resultset('Foo');
96 my $searched_rs = $self->search($resultset);
97 Calls the controller_search method on the passed in resultset with all
99 of the CGI parameters. I like to have this look something like the
100 following:
101 # Base search dispatcher, defined in MyApp::Schema::ResultSet
103 sub _build_search {
104 my $self = shift;
105 my $dispatch_table = shift;
106 my $q = shift;
107 my %search = ();
109 my %meta = ();
110 foreach ( keys %{$q} ) {
112 if ( my $fn = $dispatch_table->{$_} and $q->{$_} ) {
113 my ( $tmp_search, $tmp_meta ) = $fn->( $q->{$_} );
114 %search = ( %search, %{$tmp_search} );
115 %meta = ( %meta, %{$tmp_meta} );
116 }
117 }
118 return $self->search(\%search, \%meta);
120 }
121 # search method in specific resultset
123 sub controller_search {
124 my $self = shift;
125 my $params = shift;
126 return $self->_build_search({
127 status => sub {
128 return { 'repair_order_status' => shift }, {};
129 },
130 part_id => sub {
131 return {
132 'lineitems.part_id' => { -like => q{%}.shift( @_ ).q{%} }
133 }, { join => 'lineitems' };
134 },
135 serial => sub {
136 return {
137 'lineitems.serial' => { -like => q{%}.shift( @_ ).q{%} }
138 }, { join => 'lineitems' };
139 },
140 id => sub {
141 return { 'id' => shift }, {};
142 },
143 customer_id => sub {
144 return { 'customer_id' => shift }, {};
145 },
146 repair_order_id => sub {
147 return {
148 'repair_order_id' => { -like => q{%}.shift( @_ ).q{%} }
149 }, {};
150 },
151 },$params
152 );
153 }
154 sort
156 my $resultset = $self->schema->resultset('Foo');
157 my $result = $self->sort($resultset);
158 Exactly the same as search, except calls controller_sort. Here is how
160 I use it:
161 # Base sort dispatcher, defined in MyApp::Schema::ResultSet
163 sub _build_sort {
164 my $self = shift;
165 my $dispatch_table = shift;
166 my $default = shift;
167 my $q = shift;
168 my %search = ();
170 my %meta = ();
171 my $direction = $q->{dir};
173 my $sort = $q->{sort};
174 if ( my $fn = $dispatch_table->{$sort} ) {
176 my ( $tmp_search, $tmp_meta ) = $fn->( $direction );
177 %search = ( %search, %{$tmp_search} );
178 %meta = ( %meta, %{$tmp_meta} );
179 } elsif ( $sort && $direction ) {
180 my ( $tmp_search, $tmp_meta ) = $default->( $sort, $direction );
181 %search = ( %search, %{$tmp_search} );
182 %meta = ( %meta, %{$tmp_meta} );
183 }
184 return $self->search(\%search, \%meta);
186 }
187 # sort method in specific resultset
189 sub controller_sort {
190 my $self = shift;
191 my $params = shift;
192 return $self->_build_sort({
193 first_name => sub {
194 my $direction = shift;
195 return {}, {
196 order_by => { "-$direction" => [qw{last_name first_name}] },
197 };
198 },
199 }, sub {
200 my $param = shift;
201 my $direction = shift;
202 return {}, {
203 order_by => { "-$direction" => $param },
204 };
205 },$params
206 );
207 }
208 simple_deletion
210 $self->simple_deletion({ rs => 'Foo' });
211 Deletes from the passed in resultset based on the following CGI
213 parameter:
214 to_delete - values of the ids of items to delete
216 Valid arguments are:
218 rs - resultset loaded into schema
220 Note that this method uses the $rs->delete method, as opposed to
222 $rs->delete_all
223 simple_search
225 my $searched_rs = $self->simple_search({ rs => 'Foo' });
226 This method just searches on all of the CGI parameters that are not in
228 the "ignored_params" with a like "%$value%". If there are multiple
229 values it will make the search an "or" between the different values.
230 Valid arguments are:
232 rs - source loaded into schema
234 simple_sort
236 my $resultset = $self->schema->resultset('Foo');
237 my $sorted_rs = $self->simple_sort($resultset);
238 Sorts the passed in resultset based on the following CGI parameters:
240 sort - field to sort by, defaults to primarky key
242 dir - direction to sort
