DELETE causing a redirect loop?
- by robocode
I have an express app with a postgres backend where a user can add/delete recipes, and each time they do so they get an updated list of recipes. Adding a recipe is fine, but when I delete one it seems to get stuck in a redirect loop. In app.js I have
router.get('/delete/:d', delRec.deleteRecipe);
which calls the following code
exports.deleteRecipe = function(req, res){
pg.connect(conString, function(err, client) {
client.query('DELETE FROM recipes WHERE recipe_name = ', [req.params.d], function(err, result) {
if(err) {
return console.error('error running query', err);
} else if (result) {
pg.end();
console.log('deleting');
}
});
});
res.redirect('recipes');
};
If I try delete a recipe, console.log('deleting') produces
deleting
deleting
deleting
deleting
deleting
deleting

The recipes route is below (sorry that it's so convoluted)
router.get('/recipes', function(req, res) {
pg.connect(conString, function(err, client) {
if(err) {
return console.error('could not connect to postgres', err);
}
client.query('SELECT * FROM recipes', function(err, result) {
if(err) {
return console.error('error running query', err);
}
recipes = result.rows;
for(var d in recipes) {
if (recipes.hasOwnProperty(d)) {
recipeList[d] = recipes[d].recipe_name;
}
}
res.render('recipes', {recipes: recipes, recipeList: recipeList});
});
});
});
